Functor List

Module Description

The Functor List subpackage is made up of classes designed for creating functors which are themselves lists of functors to be invoked in turn. Functor list classes are an extension to the functor class hierarchy.

Class names are constructed from the base name RWTFunctorList for templatized classes or RWFunctorList for the few non-templatized classes by adding 0, 1 or 2 for the number of caller arguments.

The formal template parameters include:

S1	Type name of the functor list's first argument.
S2	Type name of the functor list's second argument.

Note

Functor lists do not provide R0, R1, or R2 classes.

Classes
class	RWFunctorList0
	A sequence of functors whose invocation takes no arguments. More...
class	RWTFunctorList1< A1 >
	A sequence of functors whose invocation takes one argument. More...
class	RWTFunctorList2< A1, A2 >
	A sequence of functors whose invocation takes two arguments. More...

Enumerations
enum	RWCallbackScope { RW_CALL_ONCE, RW_CALL_REPEATEDLY }

Enumeration Type Documentation

enum RWCallbackScope

Deprecated:

This enum is used only in deprecated APIs.

Used when adding a callback functor to a callback list, to define how many times the functor can be invoked before being automatically removed from the list.

Enumerator
RW_CALL_ONCE	Elements added to the list with this value will be removed from the list after their first invocation.
RW_CALL_REPEATEDLY	Elements added to the list with this value will remain in the list until explicitly removed.
