variable SCHEMA

const SCHEMA: string[];

This array represents the DOM schema. It encodes inheritance, properties, and events.
## Overview
Each line represents one kind of element. The element_inheritance and properties are joined using element_inheritance|properties syntax.
## Element Inheritance
The element_inheritance can be further subdivided as element1,element2,...^parentElement. Here the individual elements are separated by , (commas). Every element in the list has identical properties.
An element may inherit additional properties from parentElement If no ^parentElement is specified then "" (blank) element is assumed.
NOTE: The blank element inherits from root [Element] element, the super element of all elements.
NOTE an element prefix such as :svg: has no special meaning to the schema.
## Properties
Each element has a set of properties separated by , (commas). Each property can be prefixed by a special character designating its type:
- (no prefix): property is a string. - *: property represents an event. - !: property is a boolean. - #: property is a number. - %: property is an object.
## Query
The class creates an internal squas representation which allows to easily answer the query of if a given property exist on a given element.
NOTE: We don't yet support querying for types or events. NOTE: This schema is auto extracted from schema_extractor.ts located in the test folder, see dom_element_schema_registry_spec.ts

Given a template string and a set of available directive selectors, computes a list of matching selectors and splits them into 2 buckets: (1) eagerly used in a template and (2) directives used only in defer blocks. Similarly, returns 2 lists of pipes (eager and deferrable).
Note: deferrable directives selectors and pipes names used in @defer blocks are **candidates** and API caller should make sure that:
* A Component where a given template is defined is standalone * Underlying dependency classes are also standalone * Dependency class symbols are not eagerly used in a TS file where a host component (that owns the template) is located

class ClassPropertyMapping

class ClassPropertyMapping<T extends InputOrOutput = InputOrOutput> {}

A mapping of component property and template binding property names, for example containing the inputs of a particular directive or component.
A single component property has exactly one input/output annotation (and therefore one binding property name) associated with it, but the same binding property name may be shared across many component property names.
Allows bidirectional querying of the mapping - looking up all inputs/outputs with a given property name, or mapping from a specific class property to its binding property name.

property classPropertyNames

readonly classPropertyNames: string[];

All class property names mapped in this mapping.

property propertyNames

readonly propertyNames: string[];

All binding property names mapped in this mapping.

method [Symbol.iterator]

[Symbol.iterator]: () => IterableIterator<T>;

Implement the iterator protocol and return entry objects which contain the class and binding property names (and are useful for destructuring).

method empty

static empty: <T extends InputOrOutput>() => ClassPropertyMapping<T>;

Construct a ClassPropertyMapping with no entries.

method fromMappedObject

static fromMappedObject: <T extends InputOrOutput>(obj: {
    [classPropertyName: string]: string | T;
}) => ClassPropertyMapping<T>;

Construct a ClassPropertyMapping from a primitive JS object which maps class property names to either binding property names or an array that contains both names, which is used in on-disk metadata formats (e.g. in .d.ts files).

method getByBindingPropertyName

getByBindingPropertyName: (propertyName: string) => ReadonlyArray<T> | null;

Lookup all InputOrOutputs that use this propertyName.

method getByClassPropertyName

getByClassPropertyName: (classPropertyName: string) => T | null;

Lookup the InputOrOutput associated with a classPropertyName.

method hasBindingPropertyName

hasBindingPropertyName: (propertyName: BindingPropertyName) => boolean;

Check whether a mapping for the given property name exists.

method merge

static merge: <T extends InputOrOutput>(
    a: ClassPropertyMapping<T>,
    b: ClassPropertyMapping<T>
) => ClassPropertyMapping<T>;

Merge two mappings into one, with class properties from b taking precedence over class properties from a.

method toDirectMappedObject

toDirectMappedObject: () => { [classPropertyName: string]: string };

Convert this mapping to a primitive JS object which maps each class property directly to the binding property name associated with it.

method toJointMappedObject

toJointMappedObject: <O = T>(
    transform: (value: T) => O
) => { [classPropertyName: string]: O };

Convert this mapping to a primitive JS object which maps each class property either to itself (for cases where the binding property name is the same) or to an array which contains both names if they differ.
This object format is used when mappings are serialized (for example into .d.ts files).
Parameter transform
Function used to transform the values of the generated map.

securityContext returns the security context for the given property on the given DOM tag.
Tag and property name are statically known and cannot change at runtime, i.e. it is not possible to bind a value into a changing attribute or tag name.
The filtering is based on a list of allowed tags|attributes. All attributes in the schema above are assumed to have the 'NONE' security context, i.e. that they are safe inert string values. Only specific well known attack vectors are assigned their appropriate context.

method parseInterpolationExpression

parseInterpolationExpression: (
    expression: string,
    parseSourceSpan: ParseSourceSpan$1,
    absoluteOffset: number

Parse microsyntax template expression and return a list of bindings or parsing errors in case the given expression is invalid.
For example,
<div *ngFor="let item of items"> ^ ^ absoluteValueOffset for `templateValue` absoluteKeyOffset for `templateKey`
contains three bindings: 1. ngFor -> null 2. item -> NgForOfContext.$implicit 3. ngForOf -> items
This is apparent from the de-sugared template:
<ng-template ngFor let-item [ngForOf]="items">
Parameter templateKey
name of directive, without the * prefix. For example: ngIf, ngFor
Parameter templateValue
RHS of the microsyntax attribute
Parameter templateUrl
template filename if it's external, component filename if it's inline
Parameter absoluteKeyOffset
start of the templateKey
Parameter absoluteValueOffset
start of the templateValue

constructor

constructor(
    start: ParseLocation,
    end: ParseLocation,
    fullStart?: ParseLocation,
    details?: string
);

Create an object that holds information about spans of tokens/nodes captured during lexing/parsing of text.
Parameter start
The location of the start of the span (having skipped leading trivia). Skipping leading trivia makes source-spans more "user friendly", since things like HTML elements will appear to begin at the start of the opening tag, rather than at the start of any leading trivia, which could include newlines.
Parameter end
The location of the end of the span.
Parameter fullStart
The start of the token without skipping the leading trivia. This is used by tooling that splits tokens further, such as extracting Angular interpolations from text tokens. Such tooling creates new source-spans relative to the original token's source-span. If leading trivia characters have been skipped then the new source-spans may be incorrectly offset.
Parameter details
Additional information (such as identifier names) that should be associated with the span.

interface MaybeForwardRefExpression

interface MaybeForwardRefExpression<T extends Expression = Expression> {}

Describes an expression that may have been wrapped in a forwardRef() guard.
This is used when describing expressions that can refer to types that may eagerly reference types that have not yet been defined.

property expression

expression: T;

The unwrapped expression.

property forwardRef

forwardRef: ForwardRefHandling;

Specified whether the expression contains a reference to something that has not yet been defined, and whether the expression is still wrapped in a forwardRef() call.
If this value is ForwardRefHandling.None then the expression is safe to use as-is.
Otherwise the expression was wrapped in a call to forwardRef() and must not be eagerly evaluated. Instead it must be wrapped in a function closure that will be evaluated lazily to allow the definition of the expression to be evaluated first.
In full AOT compilation it can be safe to unwrap the forwardRef() call up front if the expression will actually be evaluated lazily inside a function call after the value of expression has been defined.
But in other cases, such as partial AOT compilation or JIT compilation the expression will be evaluated eagerly in top level code so will need to continue to be wrapped in a forwardRef() call.

Options that can be used to modify how a template is parsed by parseTemplate().

property alwaysAttemptHtmlToR3AstConversion

alwaysAttemptHtmlToR3AstConversion?: boolean;

Whether to always attempt to convert the parsed HTML AST to an R3 AST, despite HTML or i18n Meta parse errors.
This option is useful in the context of the language service, where we want to get as much information as possible, despite any errors in the HTML. As an example, a user may be adding a new tag and expecting autocomplete on that tag. In this scenario, the HTML is in an errored state, as there is an incomplete open tag. However, we're still able to convert the HTML AST nodes to R3 AST nodes in order to provide information for the language service.
Note that even when true the HTML parse and i18n errors are still appended to the errors output, but this is done after converting the HTML AST to R3 AST.

property collectCommentNodes

collectCommentNodes?: boolean;

Include HTML Comment nodes in a top-level comments array on the returned R3 AST.
This option is required by tooling that needs to know the location of comment nodes within the AST. A concrete example is @angular-eslint which requires this in order to enable "eslint-disable" comments within HTML templates, which then allows users to turn off specific rules on a case by case basis, instead of for their whole project within a configuration file.

property enableBlockSyntax

enableBlockSyntax?: boolean;

Whether the @ block syntax is enabled.

property enableI18nLegacyMessageIdFormat

enableI18nLegacyMessageIdFormat?: boolean;

Render $localize message ids with additional legacy message ids.
This option defaults to true but in the future the default will be flipped.
For now set this option to false if you have migrated the translation files to use the new $localize message id format and you are not using compile time translation merging.

property enableLetSyntax

enableLetSyntax?: boolean;

Whether the @let syntax is enabled.

property enableSelectorless

enableSelectorless?: boolean;

Whether the selectorless syntax is enabled.

property escapedString

escapedString?: boolean;

If this text is stored in a JavaScript string, then we have to deal with escape sequences.
**Example 1:**
"abc\"def\nghi"
- The \" must be converted to ". - The \n must be converted to a new line character in a token, but it should not increment the current line for source mapping.
**Example 2:**
"abc\ def"
The line continuation (\ followed by a newline) should be removed from a token but the new line should increment the current line for source mapping.

property i18nNormalizeLineEndingsInICUs

i18nNormalizeLineEndingsInICUs?: boolean;

If this text is stored in an external template (e.g. via templateUrl) then we need to decide whether or not to normalize the line-endings (from \r\n to \n) when processing ICU expressions.
If true then we will normalize ICU expression line endings. The default is false, but this will be switched in a future major release.

property leadingTriviaChars

property filePath

filePath: Expression | null;

A string literal containing the relative path of the file in which the class is defined.
The path is relative to the project root. The compiler does the best effort to find the project root (e.g., using the rootDir of tsconfig), but if it fails this field is set to null, indicating that the file path was failed to be computed. In this case, the downstream consumers of the debug info will usually ignore the lineNumber field as well and just show the className. For security reasons we never show the absolute file path and prefer to just return null here.

Whether or not this query should collect only static results.
If static is true, the query's results will be set on the component after nodes are created, but before change detection runs. This means that any results that relied upon change detection to run (e.g. results inside *ngIf or *ngFor views) will not be collected. Query results are available in the ngOnInit hook.
If static is false, the query's results will be set on the component after change detection runs. This means that the query results can contain nodes inside *ngIf or *ngFor views, but the results will not be available in the ngOnInit hook (only in the ngAfterContentInit for content hooks and ngAfterViewInit for view hooks).
Note: For signal-based queries, this option does not have any effect.

enum DeclarationListEmitMode

const enum DeclarationListEmitMode {
    Direct = 0,
    Closure = 1,
    ClosureResolved = 2,
    RuntimeResolved = 3,
}

Specifies how a list of declaration type references should be emitted into the generated code.

member Closure

Closure = 1

The list of declarations is emitted into the generated code wrapped inside a closure, which is needed when at least one declaration is a forward reference.
directives: function () { return [MyDir, ForwardDir]; },

member ClosureResolved

ClosureResolved = 2

Similar to Closure, with the addition that the list of declarations can contain individual items that are themselves forward references. This is relevant for JIT compilations, as unwrapping the forwardRef cannot be done statically so must be deferred. This mode emits the declaration list using a mapping transform through resolveForwardRef to ensure that any forward references within the list are resolved when the outer closure is invoked.
Consider the case where the runtime has captured two declarations in two distinct values:
const dirA = MyDir; const dirB = forwardRef(function() { return ForwardRef; });
This mode would emit the declarations captured in dirA and dirB as follows:
directives: function () { return [dirA, dirB].map(ng.resolveForwardRef); },

member Direct

Direct = 0

The list of declarations is emitted into the generated code as is.
directives: [MyDir],

member RuntimeResolved

RuntimeResolved = 3

enum DeferBlockDepsEmitMode

const enum DeferBlockDepsEmitMode {
    PerBlock = 0,
    PerComponent = 1,
}

Defines how dynamic imports for deferred dependencies should be emitted in the generated output: - either in a function on per-component basis (in case of local compilation) - or in a function on per-block basis (in full compilation mode)

member PerBlock

PerBlock = 0

Dynamic imports are grouped on per-block basis.
This is used in full compilation mode, when compiler has more information about particular dependencies that belong to this block.

member PerComponent

PerComponent = 1

Dynamic imports are grouped on per-component basis.
In local compilation, compiler doesn't have enough information to determine which deferred dependencies belong to which block. In this case we group all dynamic imports into a single file on per-component basis.

enum ExpressionIdentifier

enum R3SelectorScopeMode

enum R3SelectorScopeMode {
    Inline = 0,

}

How the selector scope of an NgModule (its declarations, imports, and exports) should be emitted as a part of the NgModule definition.

member Inline

Inline = 0

Emit the declarations inline into the module definition.
This option is useful in certain contexts where it's known that JIT support is required. The tradeoff here is that this emit style prevents directives and pipes from being tree-shaken if they are unused, but the NgModule is used.

member Omit

Omit = 2

Don't generate selector scopes at all.
This is useful for contexts where JIT support is known to be unnecessary.

member SideEffect

SideEffect = 1

Emit the declarations using a side effectful function call, ɵɵsetNgModuleScope, that is guarded with the ngJitMode flag.
This form of emit supports JIT and can be optimized away if the ngJitMode flag is set to false, which allows unused directives and pipes to be tree-shaken.

Any generic parameters for the component context class will be set to any.
Produces a less useful type, but is always safe to use.

member UseEmitter
