Interface MetaDataNameLocator

All Superinterfaces:

Locator

public interface MetaDataNameLocator
extends Locator

A locator for the meta data names list model that can be used to determine if a specific key is present. This locator is optionally provided by the list model exposing the meta data names of a meta data object.
Coding example:

     MetaData metaData = ...;
     ListModel namesList = metaData.getNames();
     if (namesList instanceof LocatorProvider) {          Locator locator = ((LocatorProvider) namesList).getLocator();
         if (locator instanceof MetaDataNameLocator) {              boolean containsName = ((MetaDataNameLocator) locator).contains(aName);
             ...
         } else {              // no name locator available
         }
     } else {          // no locator available!
     }
