Constructor Detail

LanguageLevelModuleExtensionImpl

public LanguageLevelModuleExtensionImpl(Module module)

LanguageLevelModuleExtensionImpl

public LanguageLevelModuleExtensionImpl(LanguageLevelModuleExtensionImpl source,
                                        boolean writable)

Method Detail

getStateModificationCount

public long getStateModificationCount()

Specified by:

getStateModificationCount in interface PersistentStateComponentWithModificationTracker<LanguageLevelState>

getInstance

public static LanguageLevelModuleExtensionImpl getInstance(Module module)

setLanguageLevel

public void setLanguageLevel(LanguageLevel languageLevel)

Specified by:

setLanguageLevel in interface LanguageLevelModuleExtension

getState

public LanguageLevelState getState()

Specified by:

getState in interface PersistentStateComponent<LanguageLevelState>

Returns:

a component state. All properties, public and annotated fields are serialized. Only values, which differ from the default (i.e., the value of newly instantiated class) are serialized. null value indicates that the returned state won't be stored, as a result previously stored state will be used.

XmlSerializer

loadState

public void loadState(LanguageLevelState state)

Description copied from interface: PersistentStateComponent

This method is called when new component state is loaded. The method can and will be called several times, if config files were externally changed while IDE was running.

State object should be used directly, defensive copying is not required.

Specified by:

loadState in interface PersistentStateComponent<LanguageLevelState>

Parameters:

state - loaded component state

XmlSerializerUtil.copyBean(Object, Object)

getModifiableModel

public ModuleExtension getModifiableModel(boolean writable)

Description copied from class: ModuleExtension

Note: don't call this method directly from client code. Use approach below instead:

   ModifiableRootModel modifiableModel = ModuleRootManager.getInstance(module).getModifiableModel();
   CompilerModuleExtension extension = modifiableModel.getModuleExtension(CompilerModuleExtension.class);
   try {
     // ...
   }
   finally {
     modifiableModel.commit();
   }
 

The point is that call to commit() on CompilerModuleExtension obtained like 'CompilerModuleExtension.getInstance(module).getModifiableModel(true)' doesn't dispose the model.

Call to ModifiableRootModel.commit() not only commits linked extensions but disposes them as well.

Specified by:

getModifiableModel in class ModuleExtension

Parameters:

writable - flag which identifies if resulting model is writable

Returns:

extension model

commit

public void commit()

Specified by:

commit in class ModuleExtension

isChanged

public boolean isChanged()

Specified by:

isChanged in class ModuleExtension

dispose

public void dispose()

Description copied from interface: Disposable

Usually not invoked directly, see class javadoc.

Specified by:

dispose in interface Disposable

getLanguageLevel

public LanguageLevel getLanguageLevel()

Specified by:

getLanguageLevel in interface LanguageLevelModuleExtension
