Member Function Documentation

virtual CallbackBase* Monitor::Utility::CallbackBase::clone (    )  const [pure virtual]

Produce a copy of a specialisation implementing this interface. Returns: Pointer to new instance. Implemented in Monitor::Utility::FuncCallback.

virtual void Monitor::Utility::CallbackBase::invoke (  const void *    invocationData = 0 )  const [pure virtual]

Invoke callback. Parameters: invocationData  Optional data to pass to callback. Implemented in Monitor::Utility::FuncCallback.

virtual int Monitor::Utility::CallbackBase::isEqual (  const CallbackBase &    other )  const [inline, virtual]

Generic equivalence test which may be overridden by specialisation implementing this interface. Parameters: other  Instance to test for equivalence with. Reimplemented in Monitor::Utility::FuncCallback. Definition at line 85 of file callback.h. References CallbackBase. Referenced by operator==.

virtual int Monitor::Utility::CallbackBase::isTarget (  const void *    testTarget )  const [pure virtual]

Test if object is the target for this callback. Returns: !0 if is target, otherwise 0. Implemented in Monitor::Utility::FuncCallback.

int Monitor::Utility::CallbackBase::operator== (  const CallbackBase &    other )  const [inline]

Equivalence operator defers test to a method overridden by specialisation implementing this interface. Parameters: other  Instance to test for equivalence with. Definition at line 76 of file callback.h. References CallbackBase, and isEqual.

virtual int Monitor::Utility::CallbackBase::set (    )  const [pure virtual]

Test if callback is set, that is can it be invoked. Returns: !0 if set and can be invoked, otherwise 0. Implemented in Monitor::Utility::FuncCallback.
