`void`	`release(ByteBuffer b)`	For RefCounted implementations using direct memory, the release method needs to be called to free references to the allocated memory.

- Method Detail
  - allocate
```
ByteBuffer allocate(int size)
```
  - release
```
void release(ByteBuffer b)
```
    For RefCounted implementations using direct memory, the release method needs to be called to free references to the allocated memory.
    
    Parameters:
    
    b - a ByteBuffer
  - isDirect
```
boolean isDirect()
```
    Indicates if this allocator will produce ByteBuffers backed by direct memory.
    
    Returns:
    
    true if direct memory backed buffers will be created by this allocator, else false
