NAME
ACE_Local_WLock - Class that acquires, renews, and releases a writer lock that is local to the process.
SYNOPSIS
#include <ace/Local_Tokens.h>
class ACE_Local_WLock : public ACE_Token_Proxy
{
public:
ACE_Local_WLock (
const ASYS_TCHAR *token_name = 0,
int ignore_deadlock = 0,
int debug = 0
);
~ACE_Local_WLock (void);
void dump (void) const;
virtual int type (void) const;
virtual ACE_Token_Proxy *clone (void) const;
protected:
ACE_Tokens *create_token (const ASYS_TCHAR *name);
};
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.
Initialization and termination.
ACE_Local_WLock (
const ASYS_TCHAR *token_name = 0,
int ignore_deadlock = 0,
int debug = 0
);
token_name uniquely id's the token. ignore_deadlock will allow deadlock to occur (useful for testing). debug prints a bunch of messages.
~ACE_Local_WLock (void);
Destructor
void dump (void) const;
Dump the state of the class.
virtual int type (void) const;
Returns ACE_RW_Token::WLOCK.
virtual ACE_Token_Proxy *clone (void) const;
Return deep copy.
