Variable Documentation

◆ DEFAULT

DEFAULT

Default behaviour: Continue with destruction, observer will be removed.

◆ CLAIM_SHARED_OWNERSHIP

CLAIM_SHARED_OWNERSHIP

The observer claims shared ownership of the target, do not destruct the object.

◆ CLAIM_EXCLUSIVE_OWNERSHIP

CLAIM_EXCLUSIVE_OWNERSHIP

The first observer/creator claims exclusive ownership of the target, do not destruct the object.

◆ KEEP_OBSERVER

KEEP_OBSERVER

Do not delete the observer (usually only makes sense if ownership is claimed).

◆ INVOKE_WITH_UNLOCKED_TARGET

INVOKE_WITH_UNLOCKED_TARGET

Ask to invoke the observer again without the target being locked (if you need to destruct associated objects).

◆ TARGET_IS_LOCKED

TARGET_IS_LOCKED

The target is locked and you must not directly or indireclty modify itself or any related objects.

◆ TARGET_HAS_EXCLUSIVE_OWNERSHIP

TARGET_HAS_EXCLUSIVE_OWNERSHIP

The target is exclusively owned and you cannot claim shared ownership.
