public class HeapChannelBufferFactory extends AbstractChannelBufferFactory
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.Constructor and Description |
---|
HeapChannelBufferFactory()
Creates a new factory whose default
ByteOrder is
ByteOrder.BIG_ENDIAN . |
HeapChannelBufferFactory(ByteOrder defaultOrder)
Creates a new factory with the specified default
ByteOrder . |
