Class CustomIGESLexer

java.lang.Object

org.antlr.runtime.BaseRecognizer

org.antlr.runtime.Lexer

org.eclipse.xtext.parser.antlr.Lexer

org.eclipse.january.geometry.xtext.parser.antlr.internal.InternalIGESLexer

org.eclipse.january.geometry.xtext.CustomIGESLexer

All Implemented Interfaces:

org.antlr.runtime.TokenSource

public class CustomIGESLexer
extends InternalIGESLexer

This class provides custom functions for properly lexing IGES files. The Hollerith, Delimiter, and Separator terminal functions are implemented here, but there definitions in the grammar are important to match for the parser.
