package org.jruby.lexer.yacc;
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 ).
public interface ISourcePosition extends PositionAware {
    
Which file does this source position live in?

Returns:
name of the source file.
	public String getFile();
    
    
Which is the first(start) line that this source position occurs on (zero-based)

Returns:
	public int getStartLine();


    
For nodes which are added to the AST which are not proper syntactical elements.
    public static final ISourcePosition INVALID_POSITION = new ISourcePosition() {
        public String getFile() {
            return "dummy";
        }
        public int getStartLine() {
            return -1;
        }
        public int getLine() {
            return -1;
        }
    };
