org.apache.synapse.util.xpath
public class: SynapseXPathFunctionContext [javadoc | source]

java.lang.Object
   org.apache.synapse.util.xpath.SynapseXPathFunctionContext

All Implemented Interfaces:
org.jaxen.FunctionContext

XPath function context to be used when resolving XPath functions when using the SynapseXPath and this resolves one function except for the standard XPath functions and Jaxen extension functions.

The function that has been resolved by this FunctionContext is; get-property(String) which is used to retrieve message context properties

org.apache.synapse.util.xpath.SynapseXPath

Constructor:

Constructor:
public SynapseXPathFunctionContext(FunctionContext parent, MessageContext synCtx) { this.parent = parent; this.synCtx = synCtx; } Initialises the function context Parameters: `parent` - the parent function context `synCtx` - message to be used for the function initialization Also see: org.jaxen.XPathFunctionContext

 public SynapseXPathFunctionContext(FunctionContext parent,
    MessageContext synCtx) {
        this.parent = parent;
        this.synCtx = synCtx;
}

Initialises the function context

Parameters:

parent - the parent function context

synCtx - message to be used for the function initialization

Method from org.apache.synapse.util.xpath.SynapseXPathFunctionContext Detail:
public Function getFunction(String namespaceURI, String prefix, String localName) throws UnresolvableException { if (localName != null && SynapseXPathConstants.GET_PROPERTY_FUNCTION.equals(localName)) { // create an instance of a synapse:get-property() // function and set it to the xpath GetPropertyFunction getPropertyFunc = new GetPropertyFunction(); getPropertyFunc.setSynCtx(synCtx); return getPropertyFunc; } // if not the get-property function then try to get it from the parent context return parent.getFunction(namespaceURI, prefix, localName); } Get the function with a given namespace and name. Only the `get-property` function is recognized by this class. Any other function will be resolved using the parent function context.

        }
        // if not the get-property function then try to get it from the parent context
        return parent.getFunction(namespaceURI, prefix, localName);
}

Only the get-property function is recognized by this class. Any other function will be resolved using the parent function context.
