Detailed Description

Action node

An Action node is a simple node in a Flow (cf. "single-line statement"). The runtime behaviour of an Action node can be customized for different contexts by applying Validities. A context-specific behaviour can be configured by choosing one out of a list of available ActionRealisations defined by the OTX Core or any OTX extension. Action nodes are in general to be treated as atomic, but there are exceptions depending on the ActionRealisation type. Exceptions are especially emphasized in the specification for the particular type of ActionRealisation.

Note

Action nodes play a central role concerning the extensibility of the OTX data model.

Syntax

action
{
    ActionRealisation realisation1 [validFor OtxLink validFor];
    ActionRealisation realisation2 [validFor OtxLink validFor];
    ...
    ActionRealisation realisationN [validFor OtxLink validFor];
}

Example

// Validities
 
private validity Validity1 = true;
 
// Global Declarations
 
public procedure main()
{
    // Local Declarations
 
    Boolean BooleanResult = false;
 
    // Flow
 
    // Action with two realizations
    action
    {
        BooleanResult = NaN == NaN validFor Validity1;
        BooleanResult = false;
    }
}

realisation

ActionRealisation [] OpenTestSystem.Otx.Core.Nodes.Node.Action.realisation

Cardinality [0..*]
Realisation of an action.

The realisation is the counterpart of the specification element for an Action node. In an action node, multiple realisation elements are allowed. At runtime, the validity of each realisation will be evaluated one by one (in the order of appearance in the OTX document). The first valid element found will be executed. Following realisations are ignored. The behaviour of the finally executed realisation element is determined by the assigned ActionRealisation, e.g. ProcedureCall, Assignment ListInsertItems etc.

Note

As long as no realisation element is set, an Action node has no runtime semantics which means that it will be skipped during execution (NOP).
