Method Detail

onActivate

public void onActivate()

Description copied from class: EnginePlugin

for developers extending the EnginePlugin object, it may be easier to use the onActivate() method which gets called when the plugin is being activated by the Engine. this is an alternative to calling registerActivateHook()

Overrides:

onActivate in class EnginePlugin

registerHooks

protected void registerHooks()

sendSpawnGenerators

protected void sendSpawnGenerators(Instance instance)

registerWorldLoaderOverrideClass

public static void registerWorldLoaderOverrideClass(java.lang.String name,
                                                    java.lang.Class loaderOverrideClass)

Register a world loader override class. The registered name is referenced by instance property InstanceClient.TEMPL_LOADER_OVERRIDE_NAME. An instance of the class is created prior to loading the instance world file. If the instance does not specify a world loader override, then DefaultWorldLoaderOverride is used.

Parameters:

name - World loader override class registered name.

loaderOverrideClass - World loader override class, must implement WorldLoaderOverride.

getWorldLoaderOverrideClass

public static java.lang.Class getWorldLoaderOverrideClass(java.lang.String name)

Get a registered spawn generator class.

getPersistentInstanceOid

public OID getPersistentInstanceOid(java.lang.String name)

Get persistent instance oid by name. The lookup is performed on the database, independent of loaded instances.

selectWorldManagerPlugin

protected final PluginStatus selectWorldManagerPlugin()

selectBestWorldManager

protected PluginStatus selectBestWorldManager(java.util.List<PluginStatus> plugins)

registerPopulationChangeCallback

public void registerPopulationChangeCallback(InstancePlugin.PopulationChangeCallback populationChangeCallback)

Register the callback that supplies the population of an instance when it changes.

Parameters:

populationChangeCallback -
