Declaration
public Func<EntityObject, Environment, IEnumerable<QueryParameter>, object> Function { get; }Property Value
| Type | Description |

Methods
Accept(ModelElementVisitor)
Accepts a visitor. Dispatches the correct visit handler in the visitor for the Permission
Declaration
public override void Accept(ModelElementVisitor visitor)Parameters
| Type | Name | Description |
|---|---|---|
| ModelElementVisitor | visitor | the visitor to accept. |
Overrides
Validate(ref IList<PropertyValidationMessage>, Boolean)
Validates a ModelElement according to certain rules.
Declaration
protected override void Validate(ref IList<PropertyValidationMessage> messages, bool validateRecursively)Parameters
| Type | Name | Description |
|---|---|---|
| System.Collections.Generic.IList<PropertyValidationMessage> | messages | An list of strings that stores that picks up the validation errors of a model element. |
| System.Boolean | validateRecursively | Indicates wheter to validate only the current model element or all its children (recursively) as well. |
Overrides
Remarks
The rules the ModelElement is validated against are dependent on the type of ModelElement that is validated. This method can be overridden to provide custom validation behavior for subclasses of ModelElement
When Validate(ref IList<PropertyValidationMessage>, Boolean) is called on a modelelement, the Validate(ref IList<PropertyValidationMessage>, Boolean) method of all children attatched to the modelelemnt are validated recursivly.
