Method Detail

processSoapArguments

protected Object[] processSoapArguments(Method soapClientMethod,
                            Object[] args)

Processes the arguments such that they will be ready to be passed into the supplied SOAP client method. This method can be overridden in the case that a particular framework must additionally process the arguments.

In the default implementation of processing arguments, if the number of arguments is too small, the argument list will be padded with null. If args is null, null will be returned.

Parameters:

soapClientMethod - the SOAP client method that will be called with the args

args - the arguments that will be processed

Returns:

the arguments ready to be passed into the soapClientMethod.

getSoapClientMethod

public Method getSoapClientMethod(T soapClient,
                         Method method)
                           throws NoSuchMethodException

Gets the method from the SOAP client that matches the supplied method.

In the default implementation, only the method name and return type will be matched.

Specified by:

getSoapClientMethod in interface SoapClientHandlerInterface<T>

Parameters:

soapClient - the SOAP client within which to search for the method

method - the method to match

Returns:

the SOAP client's matching method

Throws:

NoSuchMethodException - thrown if the SOAP client does not contain the requested method. TODO(api.arogal): Needs to check parameter types as well as name/return.

invoke

protected Object invoke(SoapCall<T> soapCall)
                 throws Exception

Takes a SoapCall object and invokes the method by reflection.

Parameters:

soapCall - contains the SOAP method, SOAP client, and args to be called

Returns:

the response from the SOAP web service

Throws:

Exception - thrown if calling the operation on the remote service fails
