Class XQueryExecutable

public class XQueryExecutable

An XQueryExecutable represents the compiled form of a query. To execute the query, it must first be loaded to form an XQueryEvaluator.

An XQueryExecutable is immutable, and therefore thread-safe. It is simplest to load a new XQueryEvaluator each time the query is to be run. However, the XQueryEvaluator is serially reusable within a single thread.

An XQueryExecutable is created by using one of the Compile methods on the XQueryCompiler class.

Property Summary
 bool IsUpdateQuery

Ask whether this is an updating query (that is, one that returns a pending update list rather than a conventional value).

 

Method Summary
 net.sf.saxon.s9api.XQueryExecutable getUnderlyingCompiledQuery()

Escape-hatch method to get the underlying Saxon implementation object if required. This provides access to methods that may not be stable from release to release.
 XQueryEvaluator Load()

Load the query to prepare it for execution.
