ClassLoadersHolder

public ClassLoadersHolder(SRepository repository,
                          ModulesWatcher modulesWatcher)

Method Detail

init

public void init()

dispose

public void dispose()

getClassLoader

@Nullable
public MPSModuleClassLoader getClassLoader(@NotNull
                                           ReloadableModule module)

getClassLoadingProgress

@NotNull
public ClassLoadersHolder.ClassLoadingProgress getClassLoadingProgress(SModuleReference mRef)

Returns:

ClassLoadersHolder.ClassLoadingProgress for the module. See the documentation of ClassLoadersHolder.ClassLoadingProgress for the description of states and a typical lifecycle of module in a repository.

doUnloadModules

public Set<SModuleReference> doUnloadModules(Set<SModuleReference> toUnload)

Parameters:

toUnload - for these modules ModuleClassLoaders were disposed

Returns:

modules which changed their ClassLoadingProgress from LAZY_LOADED or LOADED to UNLOADED.

onLazyLoaded

public Set<ReloadableModule> onLazyLoaded(Set<ReloadableModule> toLoadLazy)

Parameters:

toLoadLazy - for these modules only notifications DeployListener.onLoaded(Set, ProgressMonitor) were sent, so for DeployListener clients these modules appear to be loaded. No actual loading is performed for these modules.

Returns:

modules which changed their ClassLoadingProgress from UNLOADED to LAZY_LOADED.

doLoadModules

public void doLoadModules(Set<ReloadableModule> toLoad)

Parameters:

toLoad - for these modules ModuleClassLoaders were actually created

getModuleClassLoaderDisposer

public jetbrains.mps.classloading.MPSClassLoadersRegistry.ModuleClassLoaderDisposer getModuleClassLoaderDisposer()
