```
    Description copied from interface: CollectionService
    
    Remove the template item for this collection, if there is one. Note that since this has to remove the old template item ID from the collection record in the database, the collection record will be changed, including any other changes made; in other words, this method does an update.
    
    Specified by:
    
    removeTemplateItem in interface CollectionService
    
    Parameters:
    
    context - DSpace Context
    
    collection - Collection
    
    Throws:
    
    SQLException - if database error
    
    AuthorizeException - if authorization error
    
    IOException - if IO error

                    AuthorizeException
```
    Description copied from interface: CollectionService
    
    Add an item to the collection. This simply adds a relationship between the item and the collection - it does nothing like set an issue date, remove a personal workspace item etc. This has instant effect; update need not be called.

    Description copied from interface: DSpaceObjectService
    
    Return the dspace object where an ADMIN action right is sufficient to grant the initial authorize check.
    Default behaviour is ADMIN right on the object grant right on all other action on the object itself. Subclass should override this method as needed.
    
    Specified by:
    
    getAdminObject in interface DSpaceObjectService<Collection>

    context - DSpace context
    
    collection - DSpaceObject
    
    action - ID of action being attempted, from org.dspace.core.Constants. The ADMIN action is not a valid parameter for this method, an IllegalArgumentException should be thrown

```
    Description copied from interface: DSpaceObjectService
    
    Return the dspace object that "own" the current object in the hierarchy. Note that this method has a meaning slightly different from the getAdminObject because it is independent of the action but it is in a way related to it. It defines the "first" dspace object OTHER then the current one, where allowed ADMIN actions imply allowed ADMIN actions on the object self.
