Class ComponentEvent

java.lang.Object

org.nuxeo.runtime.ComponentEvent

public class ComponentEvent
extends Object

A component event.

The following event types are defined:

• COMPONENT_REGISTERED Sent when registering a component after the component is created
• COMPONENT_UNREGISTERED Sent when unregistering a component before the component is destroyed
• ACTIVATING_COMPONENT Sent before a component is activated
• COMPONENT_ACTIVATED Sent after the component is activated
• DEACTIVATING_COMPONENT Sent before a component is deactivated
• COMPONENT_DEACTIVATED Sent after a component is deactivated
• COMPONENT_RESOLVED Sent when a component was resolved (all dependencies are satisfied)
• COMPONENT_UNRESOLVED Sent when a component is unresolved (either it will be unregistered, either one of its dependencies is no more satisfied)
• COMPONENT_STARTED Sent when a component was started (even when component is not a java instance)
• COMPONENT_STOPPED Sent when a component was stopped (even when component is not a java instance)
• EXTENSION_REGISTEREDSent when a component contribution to an extension point is registered
• EXTENSION_UNREGISTEREDSent when a component contribution to an extension point is unregistered
• EXTENSION_PENDINGSent when a component contribution to an extension point is pending, waiting for dependencies to be resolved.
• COMPONENT_EVENT May be used by components to end custom events

Ordering of events for a given component:

• COMPONENT_REGISTERED
• COMPONENT_RESOLVED (if the component dependencies were satisfied)

• ACTIVATING_COMPONENT
• COMPONENT_ACTIVATED

• EXTENSION_PENDING (if an extension is pending)
• EXTENSION_REGISTERED (if an extension is registered)

• STARTING_COMPONENT
• COMPONENT_STARTED

• EXTENSION_UNREGISTERED (if an extension was registered)

• STOPPING_COMPONENT
• COMPONENT_STOPPED

• DEACTIVATING_COMPONENT
• COMPONENT_DEACTIVATED
• COMPONENT_UNRESOLVED
• COMPONENT_UNREGISTERED
