类 DefaultDataBufferFactory

java.lang.Object
cn.taketoday.core.io.buffer.DefaultDataBufferFactory
所有已实现的接口:
DataBufferFactory

public class DefaultDataBufferFactory extends Object implements DataBufferFactory
Default implementation of the DataBufferFactory interface. Allows for specification of the default initial capacity at construction time, as well as whether heap-based or direct buffers are to be preferred.

    • DefaultDataBufferFactory

      public DefaultDataBufferFactory()
      Creates a new DefaultDataBufferFactory with default settings.
      另请参阅:
    • 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

    • 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 of the dataBuffers argument
    • isDirect

      public boolean isDirect()
      从接口复制的说明: DataBufferFactory
      Indicates whether this factory allocates direct buffers (i.e. non-heap, native memory).
      指定者:
      isDirect 在接口中 DataBufferFactory
      返回:
      true if this factory allocates direct buffers; false otherwise
    • toString

      public String toString()
      覆盖:
      toString 在类中 Object
