Interface Native

All Known Subinterfaces:

NativeMessage

All Known Implementing Classes:

IdmsXid, NativeBase, NativeBuffer, NativeObject

public interface Native

Classes that implement the Native interface model native control blocks and provide methods to read and write their contents to buffered native data input and output streams. The native data input streams convert data to either the native format used by the native methods or a platform independent network format. Native is analagous to the Externalize interface. Native classes should be derived from the NativeObject class.
