Constructors

Permission()

Initializes a new instance of the Permission class.

Declaration
public Permission()

Permission(IEnumerable<KeyValuePair<Object, Object>>)

Initializes a new instance of the Permission class.

Declaration
public Permission(IEnumerable<KeyValuePair<object, object>> properties)
Parameters
Type Name Description
System.Collections.Generic.IEnumerable<System.Collections.Generic.KeyValuePair<System.Object, System.Object>> properties

Collection of properties.

Permission(Permission)

Initializes a new instance of the Permission class.

Declaration
public Permission(Permission element)
Parameters
Type Name Description
Permission element

The element to copy.

Properties

AccessType

Gets or sets the AccessType of the Permission.

Declaration
public PermissionType AccessType { get; set; }
Property Value
Type Description
PermissionType

Condition

Gets or sets a TCQL expression that returns either true or false.

Declaration
public string Condition { get; set; }
Property Value
Type Description
System.String

Function

Gets the CLR function for the Permission

Declaration
public Func<EntityObject, Environment, IEnumerable<QueryParameter>, object> Function { get; }
Property Value
Type Description
System.Func<EntityObject, Environment, System.Collections.Generic.IEnumerable<QueryParameter>, System.Object>
Remarks

The function needs the EntityObject on which it should operate as the first parameter.

IsDisabled

Gets or sets a value indicating whether the Permission is disalbed or not.

Declaration
public bool IsDisabled { get; set; }
Property Value
Type Description
System.Boolean

true if this instance is disalbed; otherwise, false.

Message

Gets or sets the message of the Permission.

Declaration
public string Message { get; set; }
Property Value
Type Description
System.String

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.
