Syntax
public class LogicalRelation : RelationBase, IDynamicMetaObjectProvider, INotifyPropertyChanged, IDataErrorInfo, INullable
Remarks

Logical relations can either be based on an existing relation and a join condition or by just using a join condition.

Constructors

LogicalRelation()

Initializes a new instance of the LogicalRelation class.

Declaration
public LogicalRelation()

Properties

Condition

Gets or sets the condition constraining the relation.

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

The condition can use the alias "Current" for addressing the current, source entity and the alias "Target" for addressing the target entity the logical relation is pointing to. This allows to create arbitrary correlations via non-relation guid properties, text properties or even more complex expressions.

CorrespondingRelation

Gets or sets the physical relation this logical relation corresponds to.

Declaration
public Relation CorrespondingRelation { get; set; }
Property Value
Type Description
Relation

IsNullable

Gets or sets a value indicating if the logical relation is nullable.

Declaration
public override bool IsNullable { get; set; }
Property Value
Type Description
System.Boolean
Overrides
Remarks

Always returns true, setter does nothing.

Target

Gets or sets the target of the relation.

Declaration
public override ModelEntityBase Target { get; set; }
Property Value
Type Description
ModelEntityBase
Overrides

Methods

Accept(ModelElementVisitor)

Accepts a visitor dispatching the corresponding operation to the concrete type.

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

the visitor to accept.
Overrides

SetPersistBehavior(PersistBehavior)

Sets the persist behavior of the LogicalRelation. Prevents setting PersistBehavior.Full for logical relations.

Declaration
protected override void SetPersistBehavior(PersistBehavior persistBehavior)
Parameters
Type Name Description
PersistBehavior persistBehavior

The persist behavior (PersistBehavior.MetadataOnly or PersistBehavior.None).
Overrides

ShallowCopy()

Performs a shallow copy of the current RelationBase/the derived class.

Declaration
public override RelationBase ShallowCopy()
Returns
Type Description
RelationBase

A shallow copy of the current RelationBase.
Overrides

ShallowCopy(String, PersistBehavior, Ownership, Boolean, Boolean)

Performs a shallow copy of the current RelationBase/the derived class.

Declaration
public override RelationBase ShallowCopy(string name, PersistBehavior persistBehavior, Ownership ownership, bool ignorePermissions = false, bool ignoreDefaultValues = false)
Parameters
Type Name Description
System.String name

Overridden model element name.
PersistBehavior persistBehavior

Overridden persist behavior.
Ownership ownership

Overridden ownership.
System.Boolean ignorePermissions

if set to true [ignore permissions].
System.Boolean ignoreDefaultValues

if set to true [ignore default values].
Returns
Type Description
RelationBase

A shallow copy of the current RelationBase.
