Examples with ContextSupport org.jaxen.ContextSupport used on opensource projects

Example 1 with ContextSupport

use of org.jaxen.ContextSupport in project wso2-synapse by wso2.

the class SynapseXPath method getContext.

/**
 * Create a {@link Context} wrapper for the provided object.
 * This methods implements the following class specific behavior:
 * <dl>
 *   <dt>{@link MessageContext}</dt>
 *   <dd>The XPath expression is evaluated against the SOAP envelope
 *       and the functions and variables defined by
 *       {@link SynapseXPathFunctionContext} and
 *       {@link SynapseXPathVariableContext} are
 *       available.</dd>
 *   <dt>{@link SOAPEnvelope}</dt>
 *   <dd>The variables defined by {@link SynapseXPathVariableContext}
 *       are available.</dd>
 * </dl>
 * For all other object types, the behavior is identical to
 * {@link BaseXPath#getContext(Object)}.
 * <p>
 * Note that the behavior described here also applies to all evaluation
 * methods such as {@link #evaluate(Object)} or {@link #selectSingleNode(Object)},
 * given that these methods all use {@link #getContext(Object)}.
 *
 * @see SynapseXPathFunctionContext#getFunction(String, String, String)
 * @see SynapseXPathVariableContext#getVariableValue(String, String, String)
