| * A representation of the model object '<em><b>Function Call Expression</b></em>'. |
| * <!-- end-user-doc --> |
| * |
| * <!-- begin-model-doc --> |
| * An expression that is computed by first evaluating "calledBlock" and invoking the resulting block passing the "argument" expression. The value returned by the block constitutes the value of this expression. If the block terminates with a fault, the evaluation of this expression terminates with this fault. |
| * |
| * The type of the object computed by the "parameters" expression must conform to the input parameter types of the signature called. |
| * |
| * If the calledBock evaluates to more than one callable function, all functions will be called. Invocation ordering depends on the side effect-freeness of the signatures called. |
