You can use the following APIs to call an operation
 

object callOperation(String name)
object callOperation(String name, List<?> arguments)
object callOperation(Object_ object, String name)
object callOperation(Object_ object, String name, List<?> arguments) 
object callOperation(Object_ object, String name, List<?> arguments, boolean isSynchronous)

 If the object is omitted then context (self) is used automatically.

The following example shows how to call a specified operation in ALH API by passing the operation's name

value = ALH.callOperation("test");


You can also give initial parameter values in which the arguments lists must be created by executing the following code

arguments = ALH.createList();
arguments.add("value1");
arguments.add("value2");
value = ALH.callOperation("test", arguments);

If a found Behavior value is null or an argument's size is not equal to the in or inout parameter's size of the found Behavior, an IllegalArgumentException will be thrown.

Information

Alternatively, you can use ALH API through the fUML object syntax, with $session$ from predefined variables and object.callOperation($session$, operationName, arguments). For example:

  • Object.callOperation($session$, ”test”);
  • Object.callOperation($session$, ”test”, arguments);
  • Object.callOperation($session$, ”test”, arguments, true);
