SourceMapConsumerV3

public SourceMapConsumerV3()

Method Details

parse

public void parse(String contents)
           throws SourceMapParseException

Parses the given contents containing a source map.

Specified by:

parse in interface SourceMapConsumer

Throws:

SourceMapParseException

parse

public void parse(SourceMapObject sourceMapObject,
 @Nullable SourceMapSupplier sectionSupplier)
           throws SourceMapParseException

Parses the given contents containing a source map.

Throws:

SourceMapParseException

getMappingForLine

public @Nullable com.google.debugging.sourcemap.proto.Mapping.OriginalMapping getMappingForLine(int lineNumber,
 int column)

Description copied from interface: SourceMapping

Returns the original mapping for the line number and column position found in the source map. Returns null if none is found.

Specified by:

getMappingForLine in interface SourceMapping

Parameters:

lineNumber - The line number, with the first being '1'.

column - The column index, with the first being '1'.

getOriginalSources

public Collection<String> getOriginalSources()

Specified by:

getOriginalSources in interface SourceMappingReversable

Returns:

the collection of original sources in this source mapping

getOriginalSourcesContent

public @Nullable Collection<String> getOriginalSourcesContent()

getOriginalNames

public List<String> getOriginalNames()

getReverseMapping

public Collection<com.google.debugging.sourcemap.proto.Mapping.OriginalMapping> getReverseMapping(String originalFile,
 int line,
 int column)

Description copied from interface: SourceMappingReversable

Given a source file, line, and column, return the reverse mapping (source → target). A collection is returned as in some cases (like a function being inlined), one source line may map to more then one target location. An empty collection is returned if there were no matches.

Specified by:

getReverseMapping in interface SourceMappingReversable

Parameters:

originalFile - the source file

line - the source line

column - the source column

Returns:

the reverse mapping (source → target)

getSourceRoot

public String getSourceRoot()

getExtensions

public Map<String,Object> getExtensions()

Returns all extensions and their values (which can be any json value) in a Map object.

Returns:

The extension list

visitMappings

public void visitMappings(SourceMapConsumerV3.EntryVisitor visitor)
