Interface XmlaHandler.XmlaExtra

All Known Implementing Classes:

MondrianOlap4jExtra

Enclosing class:

XmlaHandler

public static interface XmlaHandler.XmlaExtra

Extra support for XMLA server. If a connection provides this interface, the XMLA server will call methods in this interface instead of relying on the core olap4j interface.

The XmlaHandler.XmlaExtraImpl class provides a default implementation that uses the olap4j interface exclusively.
