NAME

ACE_Null_Token - No op class for nonthreaded platform protocols.

SYNOPSIS

#include <ace/Local_Tokens.h>

class ACE_Null_Token : public ACE_Token_Proxy { public: ACE_Null_Token (void); ~ACE_Null_Token (void); inline virtual int acquire (int = 0, void (* )( void *) = 0, ACE_Synch_Options & = ACE_Synch_Options::defaults ); inline virtual int renew ( int = -1, ACE_Synch_Options & = ACE_Synch_Options::defaults ); inline virtual int tryacquire (void (* /* sleep_hook */)( void *) = 0 ); inline ACE_Synch_Options::defaults); inline ACE_Synch_Options::defaults); inline virtual ACE_Token_Proxy *clone (void) const; void dump (void) const; inline virtual ACE_Tokens *create_token (const ASYS_TCHAR *); };

DESCRIPTION

This file contains definitions for the following classes:

public: 7. ACE_Token_Proxy 8. ACE_Null_Token : public ACE_Token_Proxy 9. ACE_Local_Mutex : public ACE_Token_Proxy *. ACE_Local_RLock : public ACE_Local_Mutex &. ACE_Local_WLock : public ACE_Local_Mutex private: 1. ACE_TOKEN_CONST 3. ACE_TPQ_Entry b. ACE_TSS_TPQ_Entry c. ACE_TPQ_Iterator 4. ACE_Token_Proxy_Queue 5. ACE_Tokens 6. ACE_Mutex_Token : public ACE_Tokens 12. ACE_RW_Token : public ACE_Tokens a. ACE_Token_Name

Note that the locking classes defined in this file are *not* intended to be used as general-purpose synchronization mechanisms, such as mutexes or semaphores. Instead, you should use the ACE_Recursive_Thread_Mutex, ACE_Thread_Mutex, ACE_Thread_Semaphore, etc., that are defined in $ACE_ROOT/ace/Synch.h and $ACE_ROOT/ace/Synch_T.h or the ACE_Token that's defined in $ACE_ROOT/ace/Token.h.
