    • allocate

      public CleanableDirectBuffer allocate(int capacity)
      Description copied from interface: Cleaner
      Create a direct ByteBuffer and return it alongside its cleaning mechanism, in a CleanableDirectBuffer.
      Specified by:
      allocate in interface Cleaner
      Parameters:
      capacity - The desired capacity of the direct buffer.
      Returns:

    • freeDirectBuffer

      @Deprecated public void freeDirectBuffer(ByteBuffer buffer)
      Deprecated.
      Description copied from interface: Cleaner
      Free a direct ByteBuffer if possible
      Specified by:
      freeDirectBuffer in interface Cleaner

    • hasExpensiveClean

      public boolean hasExpensiveClean()
      Description copied from interface: Cleaner
      Check if the clean operation is "relatively expensive". Expensive clean operations are fine for pooling allocators, but should be avoided for unpooled buffers.
      Specified by:
      hasExpensiveClean in interface Cleaner
      Returns:
      true if this Cleaner has an expensive clean (i.e. CleanableDirectBuffer.clean()) operation.
