resolveArgument

public Object resolveArgument(MessageContext messageContext,
                              MethodParameter parameter)
                       throws TransformerException,
                              XPathExpressionException

Description copied from interface: MethodArgumentResolver

Resolves the given parameter into a method argument.

Specified by:

resolveArgument in interface MethodArgumentResolver

Parameters:

messageContext - the current message context

parameter - the parameter to resolve to an argument. This parameter must have previously been passed to the MethodArgumentResolver.supportsParameter(MethodParameter) method of this interface, which must have returned true.

Returns:

the resolved argument. May be null.

Throws:

TransformerException

XPathExpressionException

createXPathFactory

protected XPathFactory createXPathFactory()

Create a XPathFactory that this resolver will use to create XPath objects.

Can be overridden in subclasses, adding further initialization of the factory. The resulting factory is cached, so this method will only be called once.

Returns:

the created factory
