Interface DatumImpl

All Superinterfaces:

AutoCloseable, Closeable, Datum

All Known Subinterfaces:

VarlenaWrapper

All Known Implementing Classes:

DatumImpl.Input, DatumImpl.IStream, PgNodeTreeAsXML, VarlenaWrapper.Input, VarlenaWrapper.Output, VarlenaXMLRenderer

public interface DatumImpl
extends Datum

Contains implementation for Datum.

This is also implemented by VarlenaWrapper, which is carried over from PL/Java 1.5.x, where it could originally be constructed only from native code. It has been minimally adapted to fit into this new scheme, and in future should fit more cleanly.
