Method Detail

getInstance

public static ProjectViewFileNestingService getInstance()

getState

public ProjectViewFileNestingService.MyState getState()

Specified by:

getState in interface PersistentStateComponent<ProjectViewFileNestingService.MyState>

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.

loadState

public void loadState(ProjectViewFileNestingService.MyState 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<ProjectViewFileNestingService.MyState>

Parameters:

state - loaded component state
