Binding Class Reference

#include "common/advice/binding.hpp"

Description

Conjunction of predicates to be matched against a collaboration partner for establishing an Advice connection.

The binding is defined by a textual spec in prolog-like syntax. The internal representation is immediately normalised. Typically the goal is just to create a #Matcher (Functor) to be stored for later match checks TODO type comment

friend

bindings are considered equivalent if, after normalisation, their respective definitions are identical.

Note

for bindings without variable arguments, equivalence and matching always yield the same results. Contrary to this, two bindings with some variable arguments could match, without being defined identically. For example pred(X) matches pred(u) or any other binding of the form pred(<constant_value>) ////TICKET #615 not yet implemented
