Class ByteBuffer


  • public class ByteBuffer
    extends Object
    Wrapper for WriteBuffer byte array per matrix/frame in order to support matrix/frame serialization outside global lock.
    • Constructor Detail

      • ByteBuffer

        public ByteBuffer​(long size)
    • Method Detail

      • serializeBlock

        public void serializeBlock​(CacheBlock<?> cb)
      • getSize

        public long getSize()
        Returns the buffer size in bytes.
        Returns:
        buffer size in bytes
      • isShallow

        public boolean isShallow()
      • freeMemory

        public void freeMemory()
      • checkSerialized

        public void checkSerialized()
      • isValidCapacity

        public static boolean isValidCapacity​(long size,
                                              CacheBlock<?> cb)
        Determines if byte buffer can hold the given size given this specific cache block. This call is consistent with 'serializeBlock' and allows for internal optimization according to dense/sparse representation.
        Parameters:
        size - the size
        cb - cache block
        Returns:
        true if valid capacity
