A SourceMappingReversable is a SourceMapping that can provide the reverse (source --> target) source mapping.

Method Summary
`Collection<String>`	`getOriginalSources()`
`Collection<Mapping.OriginalMapping>`	`getReverseMapping(String originalFile, int line, int column)` Given a source file, line, and column, return the reverse mapping (source --> target).

Method Detail

getOriginalSources

Collection<String> getOriginalSources()

Returns:: the collection of original sources in this source mapping

getReverseMapping

Collection<Mapping.OriginalMapping> getReverseMapping(String originalFile,
                                                      int line,
                                                      int column)

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.

Parameters:: originalFile - the source file; line - the source line; column - the source column
Returns:: the reverse mapping (source --> target)
