OCLOperators CanExecuteAction
CanExecuteAction is an OCL operator used in MDriven to check whether a given action can be executed within a specific ViewModel nesting before you actually run it with ExecuteAction. It returns a Boolean (true or false).
Syntax
selfVM.CanExecuteAction(nameofNesting, nameofAction) : Boolean
Example
Suppose you have a ViewModel nesting called "OrderList" and an action named "ApproveOrder".
selfVM.CanExecuteAction('OrderList', 'ApproveOrder')
Returns true: you can execute the 'ApproveOrder' action now.
Returns false: you cannot execute it yet (e.g., no order selected or business rule disallows it).
Arguments
nameofnesting: String
Name of ViewModel Nesting.
nameofaction: String
The ActionName to check for.
