Detailed Description

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

long ACE_Bound_Ptr_Counter::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.

void ACE_Bound_Ptr_Counter::attach_weak

(

ACE_Bound_Ptr_Counter< ACE_LOCK > *

counter

)

[inline, static]

Increase the counter reference count and return argument.

ACE_Bound_Ptr_Counter< ACE_LOCK > * ACE_Bound_Ptr_Counter::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.

ACE_Bound_Ptr_Counter< ACE_LOCK > * ACE_Bound_Ptr_Counter::create_weak

(

void

)

[inline, static]

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

long ACE_Bound_Ptr_Counter::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.

void ACE_Bound_Ptr_Counter::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.

ACE_Bound_Ptr_Counter< ACE_LOCK > * ACE_Bound_Ptr_Counter::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.

bool ACE_Bound_Ptr_Counter::object_was_deleted

(

ACE_Bound_Ptr_Counter< ACE_LOCK > *

counter

)

[inline, static]

Determine whether the object has been deleted.

Member Data Documentation

ACE_Bound_Ptr_Counter::ACE_ALLOC_HOOK_DECLARE

Declare the dynamic allocation hooks.

ACE_LOCK ACE_Bound_Ptr_Counter::lock_ [private]

Mutex variable to synchronize access to the reference counts.

long ACE_Bound_Ptr_Counter::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 Is set to -1 once the object has been destroyed to indicate to all weak pointers that it is no longer valid.

long ACE_Bound_Ptr_Counter::self_ref_count_ [private]

Reference count of this counter.
