Method Details
- getMemoryAccess
  
  public static final sun.misc.Unsafe getMemoryAccess()
- guaranteeUsability
  
  public static void guaranteeUsability()
  
  Guarantees the full usability of this class by validating if all functionality is usable.
  
  Throws:
  
  Error

- setDirectBufferDeallocator
  
  public static void setDirectBufferDeallocator(DirectBufferDeallocator deallocator)
  
  Allows to set the DirectBufferDeallocator used bydeallocateDirectBuffer(ByteBuffer) as an override to the means this class inherently tries to provide.
  See DirectBufferDeallocator for details.
  The passed instance "should" be immutable or better stateless to ensure concurrency-safe usage, but ultimately, the responsibility resides with the author of the instance's implementation.
  Passing a null resets the behavior of deallocateDirectBuffer(ByteBuffer) to the inherent logic.
  
  Parameters:
  
  deallocator - the deallocator to be used, potentially null.
