|
|
* A SourceMapConsumer instance represents a parsed source map which we can
|
|
* query for information about the original file positions by giving it a file
|
|
* position in the generated source.
|
|
*
|
|
* The only parameter is the raw source map (either as a JSON string, or
|
|
* already parsed to an object). According to the spec, source maps have the
|
|
* following attributes:
|
|
*
|
|
* - version: Which version of the source map spec this map is following.
|
|
* - sources: An array of URLs to the original source files.
|
|
* - names: An array of identifiers which can be referrenced by individual mappings.
|
|
* - sourceRoot: Optional. The URL root from which all sources are relative.
|
|
* - mappings: A string of base64 VLQs which contain the actual mappings.
|
|
* - file: The generated file this source map is associated with.
|
|
*
|
|
* Here is an example source map, taken from the source map spec[0]:
|
|
*
|
|
* {
|
|
* version : 3,
|
|
* file: "out.js",
|
|
* sourceRoot : "",
|
