Class HeapChannelBufferFactory

java.lang.Object
org.jboss.netty.buffer.AbstractChannelBufferFactory
org.jboss.netty.buffer.HeapChannelBufferFactory
All Implemented Interfaces:
ChannelBufferFactory

public class HeapChannelBufferFactory extends AbstractChannelBufferFactory
A ChannelBufferFactory which merely allocates a heap buffer with the specified capacity. HeapChannelBufferFactory should perform very well in most situations because it relies on the JVM garbage collector, which is highly optimized for heap allocation.
  • Field Details

  • Constructor Details

    • HeapChannelBufferFactory

      public HeapChannelBufferFactory()
      Creates a new factory whose default ByteOrder is ByteOrder.BIG_ENDIAN.
    • HeapChannelBufferFactory

      public HeapChannelBufferFactory(ByteOrder defaultOrder)
      Creates a new factory with the specified default ByteOrder.
      Parameters:
      defaultOrder - the default ByteOrder of this factory
  • Method Details

    • getInstance

      public static ChannelBufferFactory getInstance()
    • getInstance

      public static ChannelBufferFactory getInstance(ByteOrder endianness)
    • getBuffer

      public ChannelBuffer getBuffer(ByteOrder order, int capacity)
      Description copied from interface: ChannelBufferFactory
      Returns a ChannelBuffer with the specified endianness and capacity.
      Parameters:
      order - the endianness of the returned ChannelBuffer
      capacity - the capacity of the returned ChannelBuffer
      Returns:
      a ChannelBuffer with the specified endianness and capacity, whose readerIndex and writerIndex are 0
    • getBuffer

      public ChannelBuffer getBuffer(ByteOrder order, byte[] array, int offset, int length)
      Description copied from interface: ChannelBufferFactory
      Returns a ChannelBuffer whose content is equal to the sub-region of the specified array. Depending on the factory implementation, the returned buffer could wrap the array or create a new copy of the array.
      Parameters:
      order - the endianness of the returned ChannelBuffer
      array - the byte array
      offset - the offset of the byte array
      length - the length of the byte array
      Returns:
      a ChannelBuffer with the specified content, whose readerIndex and writerIndex are 0 and (length - offset) respectively
    • getBuffer

      public ChannelBuffer getBuffer(ByteBuffer nioBuffer)
      Description copied from interface: ChannelBufferFactory
      Returns a ChannelBuffer whose content is equal to the sub-region of the specified nioBuffer. Depending on the factory implementation, the returned buffer could wrap the nioBuffer or create a new copy of the nioBuffer.
      Parameters:
      nioBuffer - the NIO ByteBuffer
      Returns:
      a ChannelBuffer with the specified content, whose readerIndex and writerIndex are 0 and nioBuffer.remaining() respectively
