构造器详细资料

• DefaultDataBufferFactory

  public DefaultDataBufferFactory()

  Creates a new DefaultDataBufferFactory with default settings.

• DefaultDataBufferFactory

  public DefaultDataBufferFactory​(boolean preferDirect)

  Creates a new DefaultDataBufferFactory, indicating whether direct buffers should be created by allocateBuffer() and allocateBuffer(int).

  参数:

  preferDirect - true if direct buffers are to be preferred; false otherwise

• DefaultDataBufferFactory

  public DefaultDataBufferFactory​(boolean preferDirect,
                                  int defaultInitialCapacity)

  Creates a new DefaultDataBufferFactory, indicating whether direct buffers should be created by allocateBuffer() and allocateBuffer(int), and what the capacity is to be used for allocateBuffer().

  参数:

  preferDirect - true if direct buffers are to be preferred; false otherwise

方法详细资料

• allocateBuffer

  public DefaultDataBuffer 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 DefaultDataBuffer 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 DefaultDataBuffer 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 DefaultDataBuffer 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

• join

  public DefaultDataBuffer 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 creates a single DefaultDataBuffer to contain the data in dataBuffers.

  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

• toString

  public String toString()

  覆盖:

  toString 在类中 Object
