Class XPathExecutable

net.sf.saxon.s9api.XPathExecutable
public class XPathExecutable
extends java.lang.Object
An XPathExecutable represents the compiled form of an XPath expression.
To evaluate the expression, it must first be loaded to form an
XPathSelector
.
An XPathExecutable is immutable, and therefore thread-safe. It is simplest to load
a new XPathSelector each time the expression is to be evaluated. However, the XPathSelector
is serially reusable within a single thread.
An XPathExecutable is created by using the
XPathCompiler.compile(String)
method
on the
XPathCompiler
class.
getUnderlyingExpression
public XPathExpression getUnderlyingExpression()
Get the underlying implementation object representing the compiled XPath expression.
This method provides access to lower-level Saxon classes and methods which may be subject to change
from one release to the next.
- the underlying compiled XPath expression.
getUnderlyingStaticContext
public StaticContext getUnderlyingStaticContext()
Get the underlying implementation object representing the static context of the compiled
XPath expression. This method provides access to lower-level Saxon classes and methods which may be
subject to change from one release to the next.
- the underlying static context.
load
public XPathSelector load()
Load the compiled XPath expression to prepare it for execution.
- An XPathSelector. The returned XPathSelector can be used to set up the
dynamic context, and then to evaluate the expression.
