public class CrowdOsgiContainerManager
extends com.atlassian.plugin.osgi.container.felix.FelixOsgiContainerManager

Method Detail

getOsgiComponentOfType

public <T> T getOsgiComponentOfType(Class<T> clazz)

Retrieves and returns a public component from OSGi land via its class name. This method can be used to retrieve a component provided via a plugins2 OSGi bundle. Please note that components returned via this method should NEVER be cached (e.g. in a field) as they may be refreshed at any time as a plugin is enabled/disabled or the ComponentManager is reinitialised (after an XML import).

Added as part of the fix for JRADEV-6195.

Parameters:

clazz - The interface class as a String

Returns:

the component, or null if not found

public void stop()
          throws com.atlassian.plugin.osgi.container.OsgiContainerException

Specified by:

Overrides:

stop in class com.atlassian.plugin.osgi.container.felix.FelixOsgiContainerManager

Throws:

com.atlassian.plugin.osgi.container.OsgiContainerException
