Detailed Description

The weak handle of a MLMemoryBlock.

It is used to keep a reference to memory blocks in the cache list, but you cannot access the memory block until you assign this weak handle to a strong handle of type MLMemoryBlockHandle.

Constructor & Destructor Documentation

◆ MLWeakMemoryBlockHandle() [1/3]

MLWeakMemoryBlockHandle::MLWeakMemoryBlockHandle ( )

Creates a weak memory block handle that is null.

◆ MLWeakMemoryBlockHandle() [2/3]

MLWeakMemoryBlockHandle::MLWeakMemoryBlockHandle ( const MLMemoryBlockHandle & memoryBlockHandle )

Creates a weak memory block handle from the the strong handle.

If the memory block of strong handle is no more referenced by any strong handle, then it is added to the cache list.

◆ MLWeakMemoryBlockHandle() [3/3]

MLWeakMemoryBlockHandle::MLWeakMemoryBlockHandle ( const MLWeakMemoryBlockHandle & weakMemoryBlockHandle )

Creates a weak memory block handle from another weak handle.

◆ ~MLWeakMemoryBlockHandle()

MLWeakMemoryBlockHandle::~MLWeakMemoryBlockHandle ( )

If this is the last weak handle of the memory block, and no strong handle references it, then the memory block is removed from the cache list and deleted.
