Class NativeBuffer

java.lang.Object
  ca.idms.io.TraceObject
      ca.idms.io.NativeObject
          ca.idms.io.NativeBuffer

All Implemented Interfaces:

Native, Trace

public class NativeBuffer
extends NativeObject

A NativeBuffer is used to pass a data buffer between NativeDataInput and NativeDataOutput streams. The readNative and writeNative methods pass a reference to buffer instead of copying its contents. When the object is read it is linked to the buffer in the input stream. When it is written it links itself to the output stream.
