Package org.openwms.core.preferences.impl.file

Class XMLPreferenceDaoImpl

java.lang.Object

org.openwms.core.preferences.impl.file.XMLPreferenceDaoImpl

All Implemented Interfaces:

EventListener, PreferenceDao, org.springframework.context.ApplicationListener<org.openwms.core.event.ReloadFilePreferencesEvent>

@Transactional(propagation=MANDATORY)
@Repository
class XMLPreferenceDaoImpl
extends Object
implements PreferenceDao, org.springframework.context.ApplicationListener<org.openwms.core.event.ReloadFilePreferencesEvent>

A XMLPreferenceDaoImpl reads an XML file of Preferences and keeps them in-memory in a Map. An initial preferences file can be configured with a property openwms.core.config.initial-properties in the application.properties file.

On a ReloadFilePreferencesEvent the internal Map is cleared and reloaded.
