Method Detail

setInitialized

protected final void setInitialized()

Overrides:

setInitialized in class AbstractInitializableObject<C extends ApplicationContext>

checkInitialized

public final void checkInitialized()

Description copied from interface: Initializable

Checks whether initialization has yet been done and throws an NotInitializedException if not.

Specified by:

checkInitialized in interface Initializable

Overrides:

checkInitialized in class AbstractInitializableObject<C extends ApplicationContext>

awaitInitialized

public void awaitInitialized()
                      throws java.lang.InterruptedException

Description copied from interface: AsyncInitializable

Awaits the async initialization to finish.

Specified by:

awaitInitialized in interface AsyncInitializable

Throws:

java.lang.InterruptedException

initAsyc

public AsyncTask initAsyc()
                   throws java.lang.Exception

Description copied from interface: AsyncInitializable

Returns a yet unsubmitted task that will call Initializable.init() asynchronously. The caller may do something else meanwhile and at a later time call AsyncInitializable.awaitInitialized() in order to wait on the initialization to finish.

Specified by:

initAsyc in interface AsyncInitializable

Throws:

java.lang.Exception

createInitTask

protected AsyncTask createInitTask()
