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.

构造器详细资料

HeapChannelBufferFactory

public HeapChannelBufferFactory()

Creates a new factory whose default ByteOrder is ByteOrder.BIG_ENDIAN.

HeapChannelBufferFactory

public HeapChannelBufferFactory(java.nio.ByteOrder defaultOrder)

Creates a new factory with the specified default ByteOrder.

参数:

defaultOrder - the default ByteOrder of this factory

方法详细资料

getInstance

public static ChannelBufferFactory getInstance()

getInstance

public static ChannelBufferFactory getInstance(java.nio.ByteOrder endianness)

getBuffer

public ChannelBuffer getBuffer(java.nio.ByteOrder order,
                      int capacity)

从接口复制的说明: ChannelBufferFactory

Returns a ChannelBuffer with the specified endianness and capacity.

参数:

order - the endianness of the returned ChannelBuffer

capacity - the capacity of the returned ChannelBuffer

返回:

a ChannelBuffer with the specified endianness and capacity, whose readerIndex and writerIndex are 0

getBuffer

public ChannelBuffer getBuffer(java.nio.ByteOrder order,
                      byte[] array,
                      int offset,
                      int length)

从接口复制的说明: 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.

参数:

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

返回:

a ChannelBuffer with the specified content, whose readerIndex and writerIndex are 0 and (length - offset) respectively

getBuffer

public ChannelBuffer getBuffer(java.nio.ByteBuffer nioBuffer)

从接口复制的说明: 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.

参数:

nioBuffer - the NIO ByteBuffer

返回:

a ChannelBuffer with the specified content, whose readerIndex and writerIndex are 0 and nioBuffer.remaining() respectively
