Class SaxonXQPreparedExpression

java.lang.Object

net.sf.saxon.xqj.SaxonXQDynamicContext

net.sf.saxon.xqj.SaxonXQPreparedExpression

All Implemented Interfaces:

XQDynamicContext, XQPreparedExpression

public class SaxonXQPreparedExpression
extends SaxonXQDynamicContext
implements XQPreparedExpression

Saxon implementation of the XQJ interface XQPreparedExpression. This represents a compiled XQuery expression, together with the dynamic context for its evaluation. Note that this means the object should not be used in more than one thread concurrently.

Note that an expression is scrollable or not depending on the scrollability property of the XQConnection that was used to compile this expression (at the time it was compiled). If the expression is scrollable then its results are delivered in an XQSequence that supports scrolling backwards as well as forwards.

For full Javadoc details, see the XQJ interface specification.
