/**
 * <!-- begin-user-doc -->
 * A representation of the model object '<em><b>Link End Data</b></em>'.
 * <!-- end-user-doc -->
 *
 * <!-- begin-model-doc -->
 * A link end data is not an action. It is an element that identifies links. It identifies one end of a link to be read or written by the children of a link action. A link cannot be passed as a runtime value to or from an action. Instead, a link is identified by its end objects and qualifier values, if any. This requires more than one piece of data, namely, the statically-specified end in the user model, the object on the end, and the qualifier values for that end, if any. These pieces are brought together around a link end data. Each association end is identified separately with an instance of the LinkEndData class.
