GetUnqualifiedName

Краткая информация

Returns the unqualified name of the dataset sourced to the given input layer.

Описание

You can use this function to get the unqualified name of the dataset behind an ArcMap layer. When using an enterprise geodatabase, visual specifications and the aviation annotation functions require the use of unqualified feature class names. Since the name of a layer in an MXD may be different from its underlying feature class name, GetUnqualifiedName should be used to also ensure that the actual feature class name is used rather than the layer name. Similarly, different databases may fully qualify a feature class' name with additional information (such as database and user). GetUnqualifiedName ensures that if the layer is sourced to such a database, only the feature class name will be used.
