    Description copied from interface: TopicMapStoreIF
    
    PUBLIC: Gets a locator of the topic map in the store. This can be used as a locator for the topic map as a whole. The locator can be resolved to a store that holds the topic map.
    
    Specified by:
    
    getBaseAddress in interface TopicMapStoreIF
    
    Overrides:
    
    getBaseAddress in class AbstractTopicMapStore

    Description copied from interface: TopicMapStoreIF
    
    PUBLIC: Deletes the TopicMapIF from the data store. The store is closed after the topic map has been deleted. A deleted store cannot be reopened.
    If the force flag is false and the topic map contains any objects, i.e. topics and associations, a NotRemovableException will be thrown. The topic map will not be modified or closed if this is so.
    If the force flag is true, the topic map will be deleted even if it contains any objects.
    Note: if you're retrieved the store via a TopicMapReferenceIF then call delete(boolean) on the reference instead.
    
    Specified by:
