Method Detail

getSource

public Source getSource()

Description copied from interface: SourceInfo

The source code provider.

Specified by:

getSource in interface SourceInfo

getLine

public int getLine()

Specified by:

getLine in interface SourceInfo

Returns:

A 1-based line number into the original source file indicating where the source fragment begins.

getColumn

public int getColumn()

Specified by:

Returns:

A 1-based column number into the original source file indicating where the source fragment begins.

getStart

public int getStart()

Description copied from interface: SourceInfo

Returns the character index into the original source file indicating where the source fragment corresponding to this node begins.

The parser supplies useful well-defined source ranges to the nodes it creates.

Specified by:

getStart in interface SourceInfo

Returns:

the 0-based character index, or -1 if no source startPosition information is recorded for this node
