Public method Move(Int32, Int32) Moves a role to a new position inside the collection.
Public method Move(T, Int32) Moves a role to a new position inside the collection.
Public method Remove Removes the specified role from the collection.
Public method RemoveAt Removes the role at a specified index from the collection.
Public method RemoveRange Removes a range of elements from the collection.
Public method ReplaceAt Replaces a role at a specified index with a new role.
Public method Sort() Sorts the elements in the collection of element links.
Public method Sort(IComparer<T>) Sorts the elements in the collection of element links.
Public method Sort(Comparison<T>) Sorts the elements in the collection of element links.
Public method Sort(Int32, Int32, IComparer<T>) Sorts a range of elements in the collection of element links.
Public method ToArray Creates an array and copies all role players in the collection into it. (Inherited from ReadOnlyLinkedElementCollection<T>.)

Remarks

This is a strongly typed collection that refers to the opposite element instances for a relationship in which a particular element participates.

This collection provides navigation to all elements linked to an element.

Examples

This example assumes class A can have a multiplicity of class B instances. Also, class A has a property named C that represents elements linked to an instance of A.

// A a;
// B b1, b2, b3;
LinkedElementCollection<B> elementsLinkedToA = a.C;

// If class A has a multiplicity allowing only one B, the property type will be B.
// B elementLinkedToA = a.B;

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
