Function Documentation

bool op_contains (  const Structure< S > &  set, const T &  value )

Check whether a value is contained in a set. op_contains is an operator appliable on every structure; this is the "is in" relation. Definition at line 30 of file default_ops.hxx.

void swap (  vcsn::Element< S, T1 > &  e1, vcsn::Element< S, T2 > &  e2 )

Swap to Element instances with the same structure. Calling this operators is valid only if the structural elements of the two Element instances are equal. Definition at line 193 of file element_ops.hxx. References assertion, vcsn::op_swap(), Element::structure(), and Element::value(). Referenced by vcsn::confirm_and_report_match(), vcsn::do_eval(), vcsn::op_swap(), exp::swap(), Bitset::swap(), and vcsn::window_backsearch().
