           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(org.json.JSONObject sourceMapRoot)
           throws SourceMapParseException
Parses the given contents containing a source map.

Throws:
SourceMapParseException

parse

public void parse(org.json.JSONObject sourceMapRoot,
                  SourceMapSupplier sectionSupplier)
           throws SourceMapParseException
Parses the given contents containing a source map.

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

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)
