Inheritance diagram for ACE_Guard

Public Methods | |
| ACE_Guard (ACE_LOCK &l) | |
| ACE_Guard (ACE_LOCK &l, int block) | |
| Implicitly and automatically acquire (or try to acquire) the lock. If <block> is non-0 then the , else <tryacquire> it. | |
| ACE_Guard (ACE_LOCK &l, int block, int become_owner) | |
| Initialise the guard without implicitly acquiring the lock. The <become_owner> parameter indicates whether the guard should release the lock implicitly on destruction. The <block> parameter is ignored and is used here to disambiguate with the preceding constructor. | |
| ~ACE_Guard (void) | |
| Implicitly release the lock. | |
| int | acquire (void) |
| Explicitly acquire the lock. | |
| int | tryacquire (void) |
| Conditionally acquire the lock (i.e., won't block). | |
| int | release (void) |
| Explicitly release the lock, but only if it is held! | |
| void | disown (void) |
| Relinquish ownership of the lock so that it is not released implicitly in the destructor. | |
| int | locked (void) const |
| 1 if locked, 0 if couldn't acquire the lock (errno will contain the reason for this). | |
| int | remove (void) |
| Explicitly remove the lock. | |
| void | dump (void) const |
| Dump the state of an object. | |
Protected Methods | |
| ACE_Guard (ACE_LOCK *lock) | |
| Helper, meant for subclass only. | |
Protected Attributes | |
| ACE_LOCK* | lock_ |
| Pointer to the ACE_LOCK we're guarding. | |
| int | owner_ |
| Keeps track of whether we acquired the lock or failed. | |
Private Methods | |
| void | operator= (const ACE_Guard<ACE_LOCK> &) |
| ACE_Guard (const ACE_Guard<ACE_LOCK> &) | |
The class given as an actual parameter must provide at the very least the , <tryacquire>, <release>, and <remove> methods.
