`ByteBuffer`	`allocate(int size)`
`static HeapByteBufferAllocator`	`getInstance()`
`boolean`	`isDirect()`	Indicates if this allocator will produce ByteBuffers backed by direct memory.
`void`	`release(ByteBuffer b)`	For RefCounted implementations using direct memory, the release method needs to be called to free references to the allocated memory.
