NAME
ACE_Creation_Strategy - Defines the interface for specifying a creation strategy for a SVC_HANDLER.
SYNOPSIS
#include <ace/ACE_Strategies_T.h>
template<class SVC_HANDLER>
class ACE_Creation_Strategy
{
public:
ACE_Creation_Strategy (ACE_Thread_Manager * = 0);
int open (ACE_Thread_Manager * = 0);
virtual ~ACE_Creation_Strategy (void);
virtual int make_svc_handler (SVC_HANDLER *&sh);
void dump (void) const;
ACE_ALLOC_HOOK_DECLARE;
protected:
ACE_Thread_Manager *thr_mgr_;
};
DESCRIPTION
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.).
Initialization and termination methods.
ACE_Creation_Strategy (ACE_Thread_Manager * = 0);
Default constructor.
int open (ACE_Thread_Manager * = 0);
A Thread_Manager is useful when creating active objects.
virtual ~ACE_Creation_Strategy (void);
Factory method.
virtual int make_svc_handler (SVC_HANDLER *&sh);
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.
void dump (void) const;
Dump the state of an object.
ACE_ALLOC_HOOK_DECLARE;
Declare the dynamic allocation hooks.
