Detailed Description

template<class SVC_HANDLER>
class ACE_Creation_Strategy< SVC_HANDLER >

Defines the interface for specifying a creation strategy for a SVC_HANDLER.

The default behavior is to make a new SVC_HANDLER. However, subclasses can override this strategy to perform SVC_HANDLER creation in any way that they like (such as creating subclass instances of SVC_HANDLER, using a singleton, dynamically linking the handler, etc.).

Member Function Documentation

template<class SVC_HANDLER>
void ACE_Creation_Strategy< SVC_HANDLER >::dump (  void    )  const
 

Dump the state of an object.

template<class SVC_HANDLER>
ASYS_INLINE int ACE_Creation_Strategy< SVC_HANDLER >::make_svc_handler (  SVC_HANDLER *&    sh )  [virtual]
 

Create a SVC_HANDLER with the appropriate creation strategy. The default behavior of this method is to make a new <SVC_HANDLER> if <sh> == 0 (passing in the <Thread_Manager>), else <sh> is unchanged. Returns -1 on failure, else 0.
