Returns a reference to "super", an implicit reference to the super class.

_null

public static GeneratedExpression _null()

lit

public static GeneratedExpression lit(boolean b)

quotify

public static String quotify(char quote,

lit

public static GeneratedExpression lit(char c)

lit

public static GeneratedExpression lit(String s)

direct

public static GeneratedExpression direct(String source)

Creates an expression directly from a source code fragment.

This method can be used as a short-cut to create a Expression. For example, instead of _a.gt(_b), you can write it as: ExpressionFactory.direct("a>b").

Be warned that there is a danger in using this method, as it obfuscates the object model.
