Interface ISourcePosition

All Superinterfaces:

PositionAware

All Known Implementing Classes:

SimpleSourcePosition

public interface ISourcePosition
extends PositionAware

This interface is the combination of two needs: 1) A Ruby interpreter position (for warnings and errors). The interpreter only cares about filename and endLine. 2) A IDE position (offsets for showing ranges of grammatical elements). The offsets represent positions 'between' characters. So a variable 'abc' has a startOffset of 0 and an endOffset of 3 ( 0a1b2c3 ).

Field Summary

static ISourcePosition

INVALID_POSITION For nodes which are added to the AST which are not proper syntactical elements.

Method Summary

java.lang.String	getFile() Which file does this source position live in?
int	getStartLine() Which is the first(start) line that this source position occurs on (zero-based)
