Interceptor (Cordys 10.6.4 Java SDK API)

All Known Implementing Classes:

Customizer
```
public interface Interceptor
```
An object that implements this interface can be used as interceptor for UDDI request and response. The interceptor is configured in the method implementation. For example:
<implementation type="Invoke"> <serviceuri>http://d-sxcsrv.nl.mycomp.com:1080/sap/bc/soap/rfc</serviceuri> <soapaction>http://www.sap.com/Z_PORTAL_GET_CUSTOMER_ADDRES</soapaction> <authenticationType>Anonymous</authenticationType> <interceptor> <class>com.cordys.project.mycomp.uddi.MyInterceptor</class> <myparam>3</myparam> </interceptor> </implementation>
The flow when the Interceptor is created/invoked is:
When a request comes in, an Interceptor object is created
On the newly created Interceptor, method initialize(methodImplementation) is called. This allows the Interceptor object to initialize itself, based on methodImplementation
First,onRequest(request) is called
Just before sending the request to external service, onHttpRequest(httpObject, userInfo) is called
Just after receiving the response from external service,onHttpResponse(httpObject,userInfo) is called
Then, one of the following is called:
in case of success: onResponse(response)
in case of SOAP fault: onSOAPFault(soapFault)

The interceptor manipulates the XML (it does not need to copy/clone) the XML.

If an exception is thrown inside the interceptor code, the UDDI connector will throw an InterceptorException.
