Examples of org.apache.synapse.mediators.Value

org.apache.synapse.mediators.Value
Represents a Value Handling both static and dynamic(Xpath) keys. User can give Xpath expression as a key and derive real key based on message context

    private void populateParameters(MessageContext synCtx) {
        Iterator<String> params = pName2ExpressionMap.keySet().iterator();
        while (params.hasNext()) {
