Parameters:

serviceDefinition - the service definition model the invocation is based on

serviceOperation - the service operation the invocation is based on

context - the service invocation context to create a new variable container for

Returns:

the newly created and initialized service invocation variable container

completeInputParameter

protected void completeInputParameter(ServiceDefinitionModel serviceDefinitionModel,
                                      ServiceInputParameter inputParameter,
                                      ServiceInvocationVariablesContainer serviceInvocationVariablesContainer)

Internal method to process a single input parameter by looking at its definition and checking its value and adding null values for missing input parameter values in the data map.

Parameters:

serviceDefinitionModel - the service definition model the invocation is based on

inputParameter - the input parameter to be processed

serviceInvocationVariablesContainer - the container where the variable value will be added to
