public interface ExternalCallAction extends AbstractAction, CallReturnAction, FailureHandlingEntity
A representation of the model object 'External Call Action'. ExternalCallAction models the invocation of a service specified in a required interface. Therefore, it references a Role, from which the providing component can be derived, and a Signature to specify the called service. ExternalCallActions model synchronous calls to required services, i.e., the caller waits until the called service finishes execution before continuing execution itself. The PCM allows modelling asynchronous calls to required services by using an ExternalCallAction inside a ForkedBehaviour.
ExternalCallActions do not have resource demands by themselves. Component developers need to specify the resource demand of the called service in the RDSEFF of that service. The resource demand can also be calculated by analysing the providing component. This keeps the RDSEFF specification of different component developers independent from each other and makes them replaceable in an architectural model.
ExternalCallActions may contain two sets of VariableUsages specifying input parameter characterisations and output parameter characterisations respectively. VariableUsages for input parameters may only reference IN or INOUT parameters of the call's referenced signature. The random variable characterisation inside such a VariableUsage may be constants, probability distribution functions, or include a stochastic expression involving for example arithmetic operations. The latter models a dependency between the current service's own input parameters and the input parameters of the required service.The following features are supported:
