DtNoArgumentCallbackList Class Reference

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

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 invokation, so callbacks functions may safely remove themselves.

void 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.

void 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.

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.

bool DtNoArgumentCallbackList::contains ( const DtCallbackListType &  callbackList, DtCallbackFunctionType  fcn, void *  usrData  ) const

protected

Returns

True if the provided callback list currently contains an entry for the specified callback function and user data.
