```
  - listAssignableLocations
```
public Set<? extends Location> listAssignableLocations()
```
    Description copied from interface: BlobStore
    
    The get locations command returns all the valid locations for containers. A location has a scope, which is typically region or zone. A region is a general area, like eu-west, where a zone is similar to a datacenter. If a location has a parent, that implies it is within that location. For example a location can be a rack, whose parent is likely to be a zone.
    
    Specified by:
    
    listAssignableLocations in interface BlobStore
  - deleteAndVerifyContainerGone
```
protected abstract boolean deleteAndVerifyContainerGone(String container)
```
