pack-priv Class JaxenCompiled<T>

Overrides org.jdom2.xpath.util.AbstractXPathCompiled.clone.

Implements org.jdom2.xpath.XPathExpression.clone.

Doc from org.jdom2.xpath.util.AbstractXPathCompiled.clone.

Subclasses of this AbstractXPathCompile class must call super.clone() in their clone methods!

This would be a sample clone method from a subclass:

		public XPathExpression<T> clone() {
			@SuppressWarnings("unchecked")
			final MyXPathCompiled<T> ret = (MyXPathCompiled<T>)super.clone();
			// change any fields that need to be cloned.
			....
			return ret;
		}

Create a new instance of this XPathExpression that duplicates this instance.

The 'cloned' instance will have the same XPath query, namespace declarations, and variables. Changing a value associated with a variable on the cloned instance will not change this instance's values, and it is safe to run the evaluate methods on the cloned copy at the same time as this copy.

Returns:JaxenCompiled<T>

Doc from org.jdom2.xpath.XPathExpression.clone.

a new XPathExpression instance that shares the same core details as this.

Implements org.jaxen.VariableContext.getVariableValue.

Doc from org.jaxen.VariableContext.getVariableValue.

An implementation should return the value of an XPath variable based on the namespace URI and local name of the variable-reference expression.

It must not use the prefix parameter to select a variable, because a prefix could be bound to any namespace; the prefix parameter could be used in debugging output or other generated information. The prefix may otherwise be ignored.

Parameters

namespaceURI:String

the namespace URI to which the prefix parameter is bound in the XPath expression. If the variable reference expression had no prefix, the namespace URI is null.

prefix:String

the prefix that was used in the variable reference expression; this value is ignored and has no effect

localName:String

the local name of the variable-reference expression. If there is no prefix, then this is the whole name of the variable.

Returns:Object

the variable's value (which can be null)

Exceptions

UnresolvableException:

when the variable cannot be resolved

Implements org.jaxen.NamespaceContext.translateNamespacePrefixToUri.

Doc from org.jaxen.NamespaceContext.translateNamespacePrefixToUri.

Translate the provided namespace prefix into the matching bound namespace URI.

In XPath, there is no such thing as a 'default namespace'. The empty prefix always resolves to the empty namespace URI. This method should return null for the empty prefix. Similarly, the prefix "xml" always resolves to the URI "http://www.w3.org/XML/1998/namespace".

Parameters

prefix:String

the namespace prefix to resolve

Returns:String

the namespace URI bound to the prefix; or null if there is no such namespace
