public java.lang.StringescapeChar(int c, boolean forCharLiteral)
Given a character value, return a string representing the character that can be embedded inside a string literal or character literal This works for Java/C/C++ code-generation and languages with compatible special-character-escapment. Code-generators for languages should override this method.

param
c The character of interest.
param
forCharLiteral true to escape for char literal, false for string literal

		switch (c) 
		{
			    //		case GrammarAnalyzer.EPSILON_TYPE : return "<end-of-token>";
			case '\n" : return "\\n";
			case '\t" : return "\\t";
			case '\r" : return "\\r";
			case '\\" : return "\\\\";
			case '\'" : return forCharLiteral ? "\\'" : "'";
			case '"" :  return forCharLiteral ? "\"" : "\\\"";
			default :
			    if ( c<' "||c>126 ) 
				{
		        	if ( ( 0x0000 <= c ) && ( c <= 0x000F ) ) 
					{
						return "\\u000" + Integer.toString(c,16);				
					}
					else if ( ( 0x0010 <= c ) && ( c <= 0x00FF ) ) 
					{
						return "\\u00" + Integer.toString(c,16);
					}
					else if ( ( 0x0100 <= c ) && ( c <= 0x0FFF )) 
					{
		            	return "\\u0" + Integer.toString(c,16);
					}
					else 
					{
		            	return "\\u" + Integer.toString(c,16);

public java.lang.StringescapeString(java.lang.String s)
Converts a String into a representation that can be use as a literal when surrounded by double-quotes.

param
s The String to be changed into a literal

		String retval = new String();
		for (int i = 0; i < s.length(); i++)
	    {
			retval += escapeChar(s.charAt(i), false);
	    }
		return retval;
public java.lang.StringliteralChar(int c)
Given a character value, return a string representing the character literal that can be recognized by the target language compiler. This works for languages that use single-quotes for character literals. Code-generators for languages should override this method.

param
c The character of interest.

		return "'"  + escapeChar(c, true) + "'";
public java.lang.StringliteralString(java.lang.String s)
Converts a String into a string literal This works for languages that use double-quotes for string literals. Code-generators for languages should override this method.

param
s The String to be changed into a literal

		//return "\"" + escapeString(s) + "\"";
		return "@\"\"\"" + escapeString(s) + "\"\"\"";
