PolymorphicDelegate

inline

inline PolymorphicDelegate(Class * instance, RT(Class::*)(PT &) method)

Defined in src/base/include/icy/delegate.h:161

Parameters

  • instance Object on which to invoke the member function.

  • method Pointer to the member function accepting a derived PT&.

operator()

virtual const inline override

virtual inline RT operator()(IT & object) const override

Defined in src/base/include/icy/delegate.h:171

Attempts to cast object to PT; invokes the method if successful. Returns a default-constructed RT if the cast fails (packet type mismatch).

Parameters

  • object Base-type reference; cast to PT before dispatch.

Returns

Method result, or default RT on cast failure.

operator==

virtual const inline override

virtual inline bool operator==(const AbstractDelegate< RT, IT & > & that) const override

Defined in src/base/include/icy/delegate.h:181

Parameters

  • that Other delegate to compare.

Returns

True if both delegates wrap the same instance/method pair.
