§Methods

§
allGeneratedPositionsFor(originalPosition: MappedPosition): NullablePosition[]
[src]

Returns all generated line and column information for the original source, line, and column provided. If no column is provided, returns all mappings corresponding to a either the line we are searching for or the next closest line that has any mappings. Otherwise, returns all mappings corresponding to the given line and either the column we are searching for or the next closest column that has any offsets.

The only argument is an object with the following properties:

  • source: The filename of the original source.
  • line: The line number in the original source.
  • column: Optional. the column number in the original source.

and an array of objects is returned, each with the following properties:

  • line: The line number in the generated source, or null.
  • column: The column number in the generated source, or null.
§
computeColumnSpans(): void
[src]

Compute the last column for each generated mapping. The last column is inclusive.

§
destroy(): void
[src]

Free this source map consumer's associated wasm data that is manually-managed. Alternatively, you can use SourceMapConsumer.with to avoid needing to remember to call destroy.

§
eachMapping(
callback: (mapping: MappingItem) => void,
context?: any,
order?: number,
): void
[src]

Iterate over each mapping between an original source/line/column and a generated line/column in this source map.

@param callback

The function that is called with each mapping.

@param context

Optional. If specified, this object will be the value of this every time that aCallback is called.

@param order

Either SourceMapConsumer.GENERATED_ORDER or SourceMapConsumer.ORIGINAL_ORDER. Specifies whether you want to iterate over the mappings sorted by the generated file's line/column order or the original's source/line/column order, respectively. Defaults to SourceMapConsumer.GENERATED_ORDER.

§
generatedPositionFor(originalPosition: MappedPosition & {
bias?: number;
}): NullablePosition
[src]

Returns the generated line and column information for the original source, line, and column positions provided. The only argument is an object with the following properties:

  • source: The filename of the original source.
  • line: The line number in the original source.
  • column: The column number in the original source.
  • bias: Either 'SourceMapConsumer.GREATEST_LOWER_BOUND' or 'SourceMapConsumer.LEAST_UPPER_BOUND'. Specifies whether to return the closest element that is smaller than or greater than the one we are searching for, respectively, if the exact element cannot be found. Defaults to 'SourceMapConsumer.GREATEST_LOWER_BOUND'.

and an object is returned with the following properties:

  • line: The line number in the generated source, or null.
  • column: The column number in the generated source, or null.
§
hasContentsOfAllSources(): boolean
[src]

Return true if we have the source content for every source in the source map, false otherwise.

§
originalPositionFor(generatedPosition: Position & {
bias?: number;
}): NullableMappedPosition
[src]

Returns the original source, line, and column information for the generated source's line and column positions provided. The only argument is an object with the following properties:

  • line: The line number in the generated source.
  • column: The column number in the generated source.
  • bias: Either 'SourceMapConsumer.GREATEST_LOWER_BOUND' or 'SourceMapConsumer.LEAST_UPPER_BOUND'. Specifies whether to return the closest element that is smaller than or greater than the one we are searching for, respectively, if the exact element cannot be found. Defaults to 'SourceMapConsumer.GREATEST_LOWER_BOUND'.

and an object is returned with the following properties:

  • source: The original source file, or null.
  • line: The line number in the original source, or null.
  • column: The column number in the original source, or null.
  • name: The original identifier, or null.
§
sourceContentFor(source: string, returnNullOnMissing?: boolean): string | null
[src]

Returns the original source content. The only argument is the url of the original source file. Returns null if no original source content is available.
