Syntax

public class ValidationRule : ModelElement, IDynamicMetaObjectProvider, INotifyPropertyChanged, IDataErrorInfo

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

ModelElement.Accept(ModelElementVisitor)

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

ModelElement.Validate(ref IList<PropertyValidationMessage>, Boolean)

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.
