Interface DataBufferFactory

    • Method Detail

      • allocateBuffer

        DataBuffer allocateBuffer()
        Allocate a data buffer of a default initial capacity. Depending on the underlying implementation and its configuration, this will be heap-based or direct buffer.
        Returns:
        the allocated buffer
      • allocateBuffer

        DataBuffer allocateBuffer(int initialCapacity)
        Allocate a data buffer of the given initial capacity. Depending on the underlying implementation and its configuration, this will be heap-based or direct buffer.
        Parameters:
        initialCapacity - the initial capacity of the buffer to allocate
        Returns:
        the allocated buffer
      • wrap

        DataBuffer wrap(java.nio.ByteBuffer byteBuffer)
        Wrap the given ByteBuffer in a DataBuffer. Unlike allocating, wrapping does not use new memory.
        Parameters:
        byteBuffer - the NIO byte buffer to wrap
        Returns:
        the wrapped buffer
      • wrap

        DataBuffer wrap(byte[] bytes)
        Wrap the given byte array in a DataBuffer. Unlike allocating, wrapping does not use new memory.
        Parameters:
        bytes - the byte array to wrap
        Returns:
        the wrapped buffer
      • join

        DataBuffer join(java.util.List<? extends DataBuffer> dataBuffers)
        Return a new DataBuffer composed of the dataBuffers elements joined together. Depending on the implementation, the returned buffer may be a single buffer containing all data of the provided buffers, or it may be a true composite that contains references to the buffers.

        Note that the given data buffers do not have to be released, as they are released as part of the returned composite.

        Parameters:
        dataBuffers - the data buffers to be composed
        Returns:
        a buffer that is composed from the dataBuffers argument
