Method Detail

matches

public boolean matches(javax.jbi.messaging.MessageExchange exchange)

Specified by:

matches in interface Predicate

setVariableResolver

public void setVariableResolver(org.apache.servicemix.expression.MessageVariableResolver messageVariableResolver)

The variable resolver. The default one will enable the use of properties on the message, exchange, as well as making system properties and environment properties available.

Overrides:

setVariableResolver in class org.apache.servicemix.expression.JAXPXPathExpression

setUseMessageContent

public void setUseMessageContent(boolean b)

Ensure re-readability of the content if the expression also needs to access the content.

Overrides:

setUseMessageContent in class org.apache.servicemix.expression.JAXPXPathExpression

setXPath

public void setXPath(java.lang.String s)

The xpath expression used to evaluate the predicate.

Overrides:

setXPath in class org.apache.servicemix.expression.JAXPXPathExpression

setTransformer

public void setTransformer(org.apache.servicemix.jbi.jaxp.SourceTransformer sourceTransformer)

Overrides:

setTransformer in class org.apache.servicemix.expression.JAXPXPathExpression

setFactory

public void setFactory(javax.xml.xpath.XPathFactory xPathFactory)

The XPath factory. If no factory is explicitely configured, a defaut one will be created using XPathFactory.newInstance().

Overrides:

setFactory in class org.apache.servicemix.expression.JAXPXPathExpression

setFunctionResolver

public void setFunctionResolver(javax.xml.xpath.XPathFunctionResolver xPathFunctionResolver)

The function resolver.

Overrides:

setFunctionResolver in class org.apache.servicemix.expression.JAXPXPathExpression

setNamespaceContext

public void setNamespaceContext(javax.xml.namespace.NamespaceContext namespaceContext)

The namespace context to use when evaluating the xpath expression

Overrides:

setNamespaceContext in class org.apache.servicemix.expression.JAXPXPathExpression
