EnabledModuleCachingPluginAccessor

public EnabledModuleCachingPluginAccessor(PluginAccessor delegate,
 PluginEventManager pluginEventManager,
 PluginController pluginController)

Method Details

onPluginDisable

public void onPluginDisable(PluginDisabledEvent event)

Clears the enabled module cache when any plugin is disabled. This ensures old modules are never returned from disabled plugins.

Parameters:

event - The plugin disabled event

onPluginEnable

public void onPluginEnable(PluginEnabledEvent event)

Clears the cache when any plugin is enabled.

onPluginModuleEnabled

public void onPluginModuleEnabled(PluginModuleEnabledEvent event)

onPluginModuleDisabled

public void onPluginModuleDisabled(PluginModuleDisabledEvent event)

onPluginFrameworkShutdown

public void onPluginFrameworkShutdown(PluginFrameworkShutdownEvent event)

getEnabledModuleDescriptorsByClass

public <D extends ModuleDescriptor<?>> List<D> getEnabledModuleDescriptorsByClass(Class<D> descriptorClazz)

This method overrides the same method on PluginAccessor from the plugin system. We keep an up to date cache of (module descriptor class M -> collection of module descriptors of descriptor class M) so we can avoid the expensive call to the plugin system.

Specified by:

getEnabledModuleDescriptorsByClass in interface PluginAccessor

Parameters:

descriptorClazz - The module descriptor class you wish to find all enabled instances of

Returns:

A list of all instances of enabled plugin module descriptors of the specified descriptor class

getEnabledModulesByClass

public <M> List<M> getEnabledModulesByClass(Class<M> moduleClass)

This method overrides the same method on PluginAccessor from the plugin system. We keep an up to date cache of (module class M -> collection of module descriptors that have module class M) so we can avoid the expensive call to the plugin system.

Specified by:

getEnabledModulesByClass in interface PluginAccessor

Parameters:

moduleClass - The module class you wish to find all instances of

Returns:

A list of all instances of enabled plugin modules of the specified class
