Detailed Description

This class works just as DtCalllbackTable, but manages callbacks that have no arguments, and therefore don't fit in the template defined by DtCallbackList.

Note

It is safe to add and remove callbacks from this table during callback invocation, so callbacks functions may safely remove themselves.

It is safe to add and remove callbacks simultaneously from multiple threads.

typedef void(* DtNoArgumentCallbackList::DtCallbackFunctionType)(void *)

Constructor & Destructor Documentation

DtNoArgumentCallbackList::DtNoArgumentCallbackList

(

)

Default constructor.

DtNoArgumentCallbackList::DtNoArgumentCallbackList ( const DtNoArgumentCallbackList &  orig )

explicit

Copy constructor.

Exists mostly so that std::map will work on linux without C++11.

Member Function Documentation

bool DtNoArgumentCallbackList::addCallback	(	DtCallbackFunctionType	fcn,
		void *	usrData
	)

Adds a new callback to the list.

A duplicate entry is checked for first, and if found, this new function is not added.

Note

It is safe to call this from inside a callback function.

Returns

True if this was the first callback added.

bool DtNoArgumentCallbackList::removeCallback	(	DtCallbackFunctionType	fcn,
		void *	usrData
	)

Removes the specified callback from the list.

Note

It is safe to call this from inside a callback function.

Returns

True if this was the last callback removed.

void DtNoArgumentCallbackList::invokeCallbacks

(

)

Invokes all the callbacks currently on the callback list.

Note

This method must not be called by any of the callbacks it invokes.

void DtNoArgumentCallbackList::removeAll

(

)

Removes all callbacks that have been registered.

DtNoArgumentCallbackList& DtNoArgumentCallbackList::operator= ( const DtNoArgumentCallbackList &  orig )
