Deprecated.

this base class is deprecated. Use XPath3Function instead

@Deprecated
public abstract class AbstractXPathExpressionEvaluator
extends AbstractExpressionEvaluator
implements Initialisable, Disposable, MuleContextAware

Provides a base class for XPath property extractors. The XPath engine used is jaxen (http://jaxen.org) which supports XPath queries on other object models such as JavaBeans as well as Xml

Method Detail

getDeprecationMessage

protected abstract String getDeprecationMessage()

Deprecated.

setMuleContext

public void setMuleContext(MuleContext context)

Deprecated.

Specified by:

setMuleContext in interface MuleContextAware

initialise

public void initialise()
                throws InitialisationException

Deprecated.

Description copied from interface: Initialisable

Method used to perform any initialisation work. If a fatal error occurs during initialisation an InitialisationException should be thrown, causing the Mule instance to shutdown. If the error is recoverable, say by retrying to connect, a RecoverableException should be thrown. There is no guarantee that by throwing a Recoverable exception that the Mule instance will not shut down.

Specified by:

initialise in interface Initialisable

Throws:

InitialisationException - if a fatal error occurs causing the Mule instance to shutdown

RecoverableException - if an error occurs that can be recovered from

inject

public void inject()
            throws Exception

Deprecated.

Throws:

Exception

evaluate

public Object evaluate(String expression,
              MuleMessage message)

Deprecated.

Extracts a single property from the message

Specified by:

evaluate in interface ExpressionEvaluator

Parameters:

expression - the property expression or expression

message - the message to extract from

Returns:

the result of the extraction or null if the property was not found

getPayloadForXPath

protected Object getPayloadForXPath(MuleMessage message)
                             throws TransformerException

Deprecated.

Throws:

TransformerException

protected void addNamespaces(NamespaceManager manager,
                 org.jaxen.XPath xpath)

Deprecated.

getXPath

protected org.jaxen.XPath getXPath(String expression,
                       Object object)

extractResultsFromNodes

protected List<?> extractResultsFromNodes(List<?> results)

Deprecated.

dispose

public void dispose()

Deprecated.

A lifecycle method where implementor should free up any resources. If an exception is thrown it should just be logged and processing should continue. This method should not throw Runtime exceptions.

Specified by:

dispose in interface Disposable
