Constructors

ValidationRule()

Initializes a new instance of the ValidationRule class

Declaration
public ValidationRule()

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

Initializes a new instance of the ValidationRule class.

Declaration
public ValidationRule(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.

ValidationRule(ValidationRule)

Initializes a new instance of the ValidationRule class.

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

The element.

Properties

Condition

Gets or sets the condition of of the ValidationRule

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

Function

Gets the CLR function for the calculated property

Declaration
public Func<EntityObject, object> Function { get; }
Property Value
Type Description
System.Func<EntityObject, 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 validation rule 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 that should be issued if the validation fails

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

Perpetrator

Gets or sets the name of the propery that is responsible for the failing validation

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

Methods

Accept(ModelElementVisitor)

accepts a visitor. Dispatches the visit handler method for a ValidationRule

Declaration
public override void Accept(ModelElementVisitor visitor)
Parameters
Type Name Description
ModelElementVisitor visitor

the visitor to dispatch to.
Overrides

GetParticipatingMembers()

Gets the participating members of the of validation condition.

Declaration
public IEnumerable<string> GetParticipatingMembers()
Returns
Type Description
System.Collections.Generic.IEnumerable<System.String>

Returns the enumeration of participating members.

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.
