Partially implemented shared pointer representation protocol.
Declared in <bslma_sharedptrrep.h>
class SharedPtrRep;This class provides a partially implemented shared pointer representation ("letter") protocol. The class provides two counters for storing the number of shared and weak references, and functions to increment and decrement these counters. In addition, this class provides protocol methods that allow concrete implementations to specify what action should be taken when these counts reach zero. The function disposeRep is responsible for destroying this object, it is called when the reference count to this object reaches zero. Thus, the destructor of this object is declared as protected and should never be invoked.
| Name | Description |
|---|---|
SharedPtrRep [constructor] | Create a SharedPtrRep object having one shared reference and no weak references. |
acquireRef | Atomically acquire a shared reference to the shared object referred to by this representation. The behavior is undefined unless 0 < numReferences(). |
acquireWeakRef | Atomically acquire a weak reference to the shared object. |
disposeObject [virtual] | Dispose of the shared object referred to by this representation. |
disposeRep [virtual] | Dispose of this representation object. |
getDeleter [virtual] | Return a pointer to the stored deleter of the specified type. |
hasUniqueOwner | Return true if there is only one shared reference and no weak references to the object referred to by this representation, and false otherwise. |
incrementRefs | Atomically increment the number of shared references. |
numReferences | Return a "snapshot" of the current number of shared references to the shared object referred to by this representation object. |
numWeakReferences | Return a "snapshot" of the current number of weak references to the shared object referred to by this representation object. |
originalPtr [virtual] | Return the (untyped) address of the modifiable shared object referred to by this representation. |
releaseRef | Atomically release a shared reference to the shared object. |
releaseWeakRef | Atomically release a weak reference to the shared object. |
resetCountsRaw | Reset the shared and weak reference counts to the specified values. |
tryAcquireRef | Try to atomically acquire a shared reference to the shared object. |
| Name | Description |
|---|---|
managedPtrDeleter | Release the shared reference held by the specified representation. |
managedPtrEmptyDeleter | Deleter that has no effect when converting a null shared pointer. |
