getName

public String getName()

Description copied from interface: RegionDatabase

Specified by:

getName in interface RegionDatabase

loadAll

public Set<ProtectedRegion> loadAll(FlagRegistry flagRegistry)

Description copied from interface: RegionDatabase

Load all regions from storage and place them into the passed map.

The map will only be modified from one thread. The keys of each map entry will be in respect to the ID of the region but transformed to be lowercase. Until this method returns, the map may not be modified by any other thread simultaneously. If an exception is thrown, then the state in which the map is left is undefined.

The provided map should have reasonably efficient get() and put() calls in order to maximize performance.

Specified by:

loadAll in interface RegionDatabase

flagRegistry - a flag registry

Returns:

a set of loaded regions
