                                        ServiceOperation serviceOperation,
                                        ServiceInvocationContext serviceInvocationContext)

executeScriptAndGetResult

protected VariableContainer executeScriptAndGetResult(ServiceDefinitionModel serviceDefinition,
                                                      ServiceOperation serviceOperation,
                                                      ServiceInvocationContext context)

Executes the service definition using the scripting engines and the language defined in the script based service definition. The input parameters are exposed directly into the script context. The output value is captured through an output container containing the resulting data populated during script execution.

Parameters:

serviceDefinition - the service definition to be executed

serviceOperation - the service operation to be executed

context - the service invocation context used for the invocation

Returns:

the variable container which will contain the output parameters set during script execution
