Detailed Description

template<class T_type>
struct sigc::lambda< T_type >

Lambda type.

Objects of this type store a value that may be of type lambda itself. In this case, operator()() executes the lambda (a lambda is always a functor at the same time). Otherwise, operator()() simply returns the stored value. The assign and subscript operators are defined to return a lambda operator.
