Method Detail

addMapping

public void addMapping(Node node,
                       com.google.javascript.jscomp.Position startPosition,
                       com.google.javascript.jscomp.Position endPosition)

Adds a mapping for the given node. Mappings must be added in order.

Specified by:: addMapping in interface SourceMap

Parameters:: node - The node that the new mapping represents.; startPosition - The position on the starting line; endPosition - The position on the ending line.

setWrapperPrefix

public void setWrapperPrefix(String prefix)

Sets the prefix used for wrapping the generated source file before it is output. This ensures that the source map is adjusted as needed.

Specified by:: setWrapperPrefix in interface SourceMap

Parameters:: prefix - The prefix that is added before the generated source code.

setStartingPosition

public void setStartingPosition(int offsetLine,
                                int offsetIndex)

Sets the source code that exists in the buffer to which the generated code is being generated. This ensures that the source map accurately reflects the fact that the source is being appended to an existing buffer and as such, does not start at line 0, position 0 but rather some other line and position.

Specified by:: setStartingPosition in interface SourceMap

Parameters:: offsetLine - The index of the current line being printed.; offsetIndex - The column index of the current character being printed.

reset

public void reset()

Resets the source map for reuse for the generation of a new source file.

Specified by:: reset in interface SourceMap

appendTo

public void appendTo(Appendable out,
                     String name)
              throws IOException

Appends the source map in LavaBug format to the given buffer.

Specified by:: appendTo in interface SourceMap

Parameters:: out - The stream to which the map will be appended.; name - The name of the generated source file that this source map represents.
Throws:: IOException
