           throws SourceMapParseException

Parses the given contents containing a source map.

Specified by:

parse in interface SourceMapConsumer

Throws:

SourceMapParseException

parse

public void parse(String contents,
         SourceMapSupplier sectionSupplier)
           throws SourceMapParseException

Parses the given contents containing a source map.

Throws:

SourceMapParseException

parse

public void parse(com.google.gson.JsonObject sourceMapRoot,
         SourceMapSupplier sectionSupplier)
           throws SourceMapParseException

getMappingForLine

public 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 Collection<String> getOriginalSourcesContent()

getFile

public String getFile()

getSourceRoot

public String getSourceRoot()

getReverseMapping

public Collection<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)

visitMappings

public void visitMappings(SourceMapConsumerV3.EntryVisitor visitor)
