类 NettyDataBufferFactory

构造器详细资料

• NettyDataBufferFactory

  public NettyDataBufferFactory​(io.netty.buffer.ByteBufAllocator byteBufAllocator)

  Create a new NettyDataBufferFactory based on the given factory.

  参数:

  byteBufAllocator - the factory to use

  另请参阅:

  PooledByteBufAllocator, UnpooledByteBufAllocator

方法详细资料

• getByteBufAllocator

  public io.netty.buffer.ByteBufAllocator getByteBufAllocator()

  Return the ByteBufAllocator used by this factory.

• allocateBuffer

  public NettyDataBuffer allocateBuffer()

  从接口复制的说明: 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.

  指定者:

  allocateBuffer 在接口中 DataBufferFactory

  返回:

  the allocated buffer

• allocateBuffer

  public NettyDataBuffer allocateBuffer​(int initialCapacity)

  从接口复制的说明: 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.

  指定者:

  allocateBuffer 在接口中 DataBufferFactory

  参数:

  initialCapacity - the initial capacity of the buffer to allocate

  返回:

  the allocated buffer

• wrap

  public NettyDataBuffer wrap​(ByteBuffer byteBuffer)

  从接口复制的说明: DataBufferFactory
  Wrap the given ByteBuffer in a DataBuffer. Unlike allocating, wrapping does not use new memory.

  指定者:

  wrap 在接口中 DataBufferFactory

  参数:

  byteBuffer - the NIO byte buffer to wrap

  返回:

  the wrapped buffer

• wrap

  public DataBuffer wrap​(byte[] bytes)

  从接口复制的说明: DataBufferFactory
  Wrap the given byte array in a DataBuffer. Unlike allocating, wrapping does not use new memory.

  指定者:

  wrap 在接口中 DataBufferFactory

  参数:

  bytes - the byte array to wrap

  返回:

  the wrapped buffer

• wrap

  public NettyDataBuffer wrap​(io.netty.buffer.ByteBuf byteBuf)

  Wrap the given Netty ByteBuf in a NettyDataBuffer.

  参数:

  byteBuf - the Netty byte buffer to wrap

  返回:

  the wrapped buffer

• join

  public DataBuffer join​(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.

  This implementation uses Netty's CompositeByteBuf.

  指定者:

  join 在接口中 DataBufferFactory

  参数:

  dataBuffers - the data buffers to be composed

  返回:

  a buffer that is composed from the dataBuffers argument

• toByteBuf

  public static io.netty.buffer.ByteBuf toByteBuf​(DataBuffer buffer)

  Return the given Netty DataBuffer as a ByteBuf.

  Returns the native buffer if buffer is a NettyDataBuffer; returns Unpooled.wrappedBuffer(ByteBuffer) otherwise.

  参数:

  buffer - the DataBuffer to return a ByteBuf for

  返回:

  the netty ByteBuf

• toString

  public String toString()

  覆盖:

  toString 在类中 Object
