Method Detail

registerModuleDefinition

public void registerModuleDefinition(String name,
                                     ModuleDefinition moduleDefinition)

Specified by:

registerModuleDefinition in interface ModuleRegistry

registerModuleInstance

public void registerModuleInstance(String name,
                                   Object moduleInstance)

Specified by:

registerModuleInstance in interface ModuleRegistry

registerModuleVersionHandler

public void registerModuleVersionHandler(String name,
                                         ModuleVersionHandler moduleVersionHandler)

Specified by:

registerModuleVersionHandler in interface ModuleRegistry

isModuleRegistered

public boolean isModuleRegistered(String name)

Specified by:

isModuleRegistered in interface ModuleRegistry

getDefinition

public ModuleDefinition getDefinition(String name)

Specified by:

getDefinition in interface ModuleRegistry

getModuleInstance

public Object getModuleInstance(String name)

Description copied from interface: ModuleRegistry

Returns the module's instance. This is useful for modules which use a common class (i.e content or theme modules, which can typically co-exist in a system and have the same module class).

Specified by:

getModuleInstance in interface ModuleRegistry

getModuleInstance

public <T> T getModuleInstance(Class<T> moduleClass)

Description copied from interface: ModuleRegistry

Returns the module's instance. This is useful for modules of known type.

Specified by:

getModuleInstance in interface ModuleRegistry

getVersionHandler

public ModuleVersionHandler getVersionHandler(String name)

Specified by:

getVersionHandler in interface ModuleRegistry

getModuleNames

public Set<String> getModuleNames()

Description copied from interface: ModuleRegistry

Returns the names of configured modules.

Specified by:

getModuleNames in interface ModuleRegistry

Returns:

unmodifiable set of module names

getModuleDefinitions

public List<ModuleDefinition> getModuleDefinitions()

Description copied from interface: ModuleRegistry

Returns the list of known ModuleDefinitions, as ordered by the loading mechanism (typically in dependency order).

Specified by:
