Examples of net.sf.saxon.s9api.XQueryExecutable

net.sf.saxon.s9api.XQueryExecutable
An XQueryExecutable represents the compiled form of a query. To execute the query, it must first be loaded to form an {@link net.sf.saxon.s9api.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 {@link net.sf.saxon.s9api.XQueryCompiler} class.
