Interface ByteBufferPool

public interface ByteBufferPool
Object Pool that allows to borrow and release ByteBuffers according to a specific type (direct/heap).

The suggested usage pattern is: 


    ByteBuffer buffer = pool.borrow(size);
    //...using buffer...
    pool.release(buffer);

  • Method Details

    • borrow

      ByteBuffer borrow(int size, boolean zeroed)
      It returns a ByteBuffer with Buffer.capacity() >= size.

      The buffer is zeroed until size if zeroed=true, with Buffer.position()=0 and Buffer.limit()=size.

    • release

      void release(ByteBuffer buffer)
      It pools or free buffer that cannot be used anymore.

      If buffer is of a type different from the one that the pool can borrow, it will ignore it.

    • threadLocal

      static ByteBufferPool threadLocal(boolean direct)
      Factory method that creates a thread-local pool of capacity 1 of ByteBuffers of the specified type (direct/heap).
