Method Detail

addApplicationContextConfigLocation

public void addApplicationContextConfigLocation(String configLocation)

Add the location of an XML file which contains Spring bean definitions that should be included when creating the ApplicationContext. Adding locations after the application context was created has no effect.

Parameters:

configLocation - an absolute location of a configuration resource with bean definitions to load. The string should start with classpath: or file: for loading classpath or file resources.

addInitializationCompleteListener

public void addInitializationCompleteListener(InitializationCompleteListener listener)

addInitializationCondition

public void addInitializationCondition(String conditionId)

addInitializer

public void addInitializer(CustomInitializer initializer)

Add an initializer that will be called during initializeApplication() after the core components were initialized.

Parameters:

initializer - the additional initializer

createApplicationContext

public void createApplicationContext()

Create the Spring ApplicationContext and inform the ApplicationPreparedCallback. If the context was already created the call is ignored.

Throws:

ApplicationInitializationException - in case the ApplicationContext cannot be created

fulfillInitializationCondition

public void fulfillInitializationCondition(String conditionId)

getInitializationStatus

public InitializationStatus getInitializationStatus()

initializeApplication

public void initializeApplication()
                           throws ApplicationInitializationException

Initializes the application.

Throws:

ApplicationInitializationException - in case something goes wrong

isCoreInitialized

public boolean isCoreInitialized()

Returns:

true if the core is initialized

isInitialized

public boolean isInitialized()

Returns:

true if the core is initialized and all init conditions are fulfilled

setApplicationPreparedCallback

public void setApplicationPreparedCallback(ApplicationPreparedCallback applicationPreparedCallback)

Set the callback to invoke after building the Spring ApplicationContext is completed. If Communote is already installed this callback is invoked within the startup process. If Communote is not yet installed this callback is called as soon as the installation is done. The callback is only invoked once. Setting the callback after startup has no effect.

Parameters:

applicationPreparedCallback - the callback to invoke

shutdown

public void shutdown()

Shutdown the core components and reset the application context. Additional application config locations, custom initializers and complete listeners are not removed.
