Method Detail

getBean

public static <T> T getBean(java.lang.String strName)
Return an instance, which may be shared or independent, of the given bean name. This method allows a Spring BeanFactory to be used as a replacement for the Singleton or Prototype design pattern.
The bean is retreived from the main context defined in the WEB-INF/conf/core_context.xml.

Parameters:
strName - The bean's name
Returns:
The instance of the bean

getPluginBean

@Deprecated
public static java.lang.Object getPluginBean(java.lang.String strPluginName,
                                                        java.lang.String strName)
Deprecated. use getBean(String) instead

Return an instance of the given bean name loaded by the a Spring BeanFactory. The bean is retreived from a plugin context defined in the WEB-INF/conf/plugins/[plugin_name]_context.xml.

Parameters:
strPluginName - The Plugin's name
strName - The bean's name
Returns:
The instance of the bean

init

public static void init()
                 throws LuteceInitException
Initialize a global Application Context containing all beans (core + plugins) Now uses GenericApplicationContext for better performances. A wrong formatted file will not block block context to be built (without the file), but a wrong bean (i.e. cannot be instantiated) will cause a full context failure. Context is less "failure-friendly"

Throws:
LuteceInitException - The lutece init exception
Since:
2.4

getContext

public static org.springframework.context.ApplicationContext getContext()
Gets the application context

Returns:
The application context

getBeansOfType

public static <T> java.util.List<T> getBeansOfType(java.lang.Class<T> classDef)
Returns a list of bean among all that implements a given interface or extends a given class

Type Parameters:
T - The class type
Parameters:
classDef - The class type
Returns:
A list of beans

processPluginEvent

public void processPluginEvent(PluginEvent event)
Process a plugin event

Specified by:
processPluginEvent in interface PluginEventListener
Parameters:
event - The event to process
