Description copied from class: Pattern

Visit a pattern recursively, creating two products: An expression that will examine a value to determine whether it matches a pattern, building an output tuple of all value fragments which will be bound to variables. An expression transformer that will examine such an output tuple and bind its elements to variables in a given expression.

Specified by:

process in class Pattern

Parameters:

fragment - A variable holding the current fragment of the value to be matched

visitor - A visitor object which accumulates an expression and a transformer

Throws:

PatternException
