Lock()

const void* Lock

(

)

const

Locks the WeakRefTarget.

Note

After locking you must unlock as soon as possible, especially calling any method with unknown behaviour can easily lead to a deadlock. THREADSAFE.

Returns

Pointer to the current target.

Unlock()

void Unlock

(

const void *

target

)

const

Unlocks the WeakRefTarget. THREADSAFE.

Parameters

[in]

target

Pointer to the (new) target to be stored.

operator Bool()

operator Bool ( ) const

explicit

Checks if there currently is a target.

Returns

True if there currently is a target, otherwise false.

GetCurrent()

const void* GetCurrent

(

)

const

Returns the current target pointer. Use Lock() and Unlock() to get a thread-safe pointer.

UnlockCurrent()

void UnlockCurrent

(

)

const

Unlocks the current target.

Swap()

void Swap	(	const void *	oldTarget,
		const void *	newTarget
	)

Swaps old and new target.

Note

Use only if oldTarget is guaranteed to be valid, otherwise this will result in a freeze.

Parameters

[in]	oldTarget	Pointer to the old target.
[in]	newTarget	Pointer to the new target to be stored.
