Detailed Description

template<class ACE_LOCK>
class ACE_Bound_Ptr_Counter< ACE_LOCK >

An ACE_Bound_Ptr_Counter<ACE_LOCK> object encapsulates an object reference count.

Do not use this class directly, use ACE_Strong_Bound_Ptr or ACE_Weak_Bound_Ptr instead.

Member Function Documentation

template<class ACE_LOCK >

long ACE_Bound_Ptr_Counter< ACE_LOCK >::attach_strong

(

ACE_Bound_Ptr_Counter< ACE_LOCK > *

counter

)

[inline, static]

Increase both the object and counter reference counts and return the new object reference count. A return value of -1 indicates that the object has already been destroyed.

template<class ACE_LOCK >

void ACE_Bound_Ptr_Counter< ACE_LOCK >::attach_weak

(

ACE_Bound_Ptr_Counter< ACE_LOCK > *

counter

)

[inline, static]

Increase the counter reference count and return argument.

template<class ACE_LOCK >

ACE_Bound_Ptr_Counter< ACE_LOCK > * ACE_Bound_Ptr_Counter< ACE_LOCK >::create_strong

(

void

)

[inline, static]

Create a ACE_Bound_Ptr_Counter<ACE_LOCK> and initialize the reference count to indicate ownership by a strong pointer.

template<class ACE_LOCK >

ACE_Bound_Ptr_Counter< ACE_LOCK > * ACE_Bound_Ptr_Counter< ACE_LOCK >::create_weak

(

void

)

[inline, static]

Create a ACE_Bound_Ptr_Counter<ACE_LOCK> and initialize the reference count to indicate no ownership.

template<class ACE_LOCK >

long ACE_Bound_Ptr_Counter< ACE_LOCK >::detach_strong

(

ACE_Bound_Ptr_Counter< ACE_LOCK > *

counter

)

[inline, static]

Decreases both the object and counter reference counts and deletes whichever has no more references. Returns the new object reference count.

template<class ACE_LOCK >

void ACE_Bound_Ptr_Counter< ACE_LOCK >::detach_weak

(

ACE_Bound_Ptr_Counter< ACE_LOCK > *

counter

)

[inline, static]

Decreases the counter reference count and deletes the counter if it has no more references.

template<class ACE_LOCK >

ACE_Bound_Ptr_Counter< ACE_LOCK > * ACE_Bound_Ptr_Counter< ACE_LOCK >::internal_create

(

long

init_obj_ref_count

)

[inline, static, private]

Allocate a new ACE_Bound_Ptr_Counter<ACE_LOCK> instance, returning NULL if it cannot be created.

template<class ACE_LOCK >

bool ACE_Bound_Ptr_Counter< ACE_LOCK >::object_was_deleted

(

ACE_Bound_Ptr_Counter< ACE_LOCK > *

counter

)

[inline, static]

Determine whether the object has been deleted.

Member Data Documentation

template<class ACE_LOCK >

ACE_Bound_Ptr_Counter< ACE_LOCK >::ACE_ALLOC_HOOK_DECLARE

Declare the dynamic allocation hooks.

template<class ACE_LOCK >

ACE_LOCK ACE_Bound_Ptr_Counter< ACE_LOCK >::lock_ [private]

Mutex variable to synchronize access to the reference counts.

template<class ACE_LOCK >

long ACE_Bound_Ptr_Counter< ACE_LOCK >::obj_ref_count_ [private]

Reference count of underlying object. Is set to -1 once the object has been destroyed to indicate to all weak pointers that it is no longer valid.

template<class ACE_LOCK >

long ACE_Bound_Ptr_Counter< ACE_LOCK >::self_ref_count_ [private]

Reference count of this counter.
