Package com.saxonica.ee.update Description

This package contains classes used to support XQuery Update. This includes both compile-time classes and run-time support.

None of these classes will be used directly by typical user applications.

The UpdateParser is a subclass of net.sf.saxon.query.QueryParser, and contains the additional code needed to parse the Update extensions to the XQuery grammar.

Classes such as InsertExpression, DeleteExpression , RenameExpression represent updating expressions on the expression tree.

The class PendingUpdateListImpl represents the run-time pending update list, and the classes InsertAction, DeleteAction, RenameAction and so on are entries on this list.
