  • Constructor Details

    • JettyDataBufferFactory

      public JettyDataBufferFactory()
      Creates a new JettyDataBufferFactory with default settings.

    • JettyDataBufferFactory

      public JettyDataBufferFactory(boolean preferDirect)
      Creates a new JettyDataBufferFactory, indicating whether direct buffers should be created by allocateBuffer() and allocateBuffer(int).
      Parameters:
      preferDirect - true if direct buffers are to be preferred; false otherwise

    • JettyDataBufferFactory

      public JettyDataBufferFactory(boolean preferDirect, int defaultInitialCapacity)
      Creates a new JettyDataBufferFactory, indicating whether direct buffers should be created by allocateBuffer() and allocateBuffer(int), and what the capacity is to be used for allocateBuffer().
      Parameters:
      preferDirect - true if direct buffers are to be preferred; false otherwise

  • Method Details

    • allocateBuffer

      @Deprecated public JettyDataBuffer allocateBuffer()
      Deprecated.
      Description copied from interface: DataBufferFactory
      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.
      Specified by:
      allocateBuffer in interface DataBufferFactory
      Returns:
      the allocated buffer

    • allocateBuffer

      public JettyDataBuffer allocateBuffer(int initialCapacity)
      Description copied from interface: DataBufferFactory
      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.
      Specified by:
      allocateBuffer in interface DataBufferFactory
      Parameters:
      initialCapacity - the initial capacity of the buffer to allocate
      Returns:
      the allocated buffer

    • wrap

      public JettyDataBuffer wrap(ByteBuffer byteBuffer)
      Description copied from interface: DataBufferFactory
      Wrap the given ByteBuffer in a DataBuffer. Unlike allocating, wrapping does not use new memory.
      Specified by:
      wrap in interface DataBufferFactory
      Parameters:
      byteBuffer - the NIO byte buffer to wrap
      Returns:
      the wrapped buffer

    • wrap

      public JettyDataBuffer wrap(byte[] bytes)
      Description copied from interface: DataBufferFactory
      Wrap the given byte array in a DataBuffer. Unlike allocating, wrapping does not use new memory.
      Specified by:
      wrap in interface DataBufferFactory
      Parameters:
      bytes - the byte array to wrap
      Returns:
      the wrapped buffer

    • wrap

      public JettyDataBuffer wrap(org.eclipse.jetty.io.Content.Chunk chunk)

    • join

      public JettyDataBuffer join(List<? extends DataBuffer> dataBuffers)
      Description copied from interface: DataBufferFactory
      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.

      Specified by:
      join in interface DataBufferFactory
      Parameters:
      dataBuffers - the data buffers to be composed
      Returns:
      a buffer that is composed of the dataBuffers argument

    • isDirect

      public boolean isDirect()
      Description copied from interface: DataBufferFactory
      Indicates whether this factory allocates direct buffers (i.e. non-heap, native memory).
      Specified by:
      isDirect in interface DataBufferFactory
      Returns:
      true if this factory allocates direct buffers; false otherwise
