Class FileEventTracker

java.lang.Object

org.nuxeo.runtime.model.DefaultComponent

org.nuxeo.runtime.trackers.files.FileEventTracker

All Implemented Interfaces:

Adaptable, Component, Extensible, TimestampedService

public class FileEventTracker
extends DefaultComponent

Files event tracker which delete files once the runtime leave the threads or at least once the associated marker object is garbaged. Note: for being backward compatible you may disable the thread events tracking by black-listing the default configuration component "org.nuxeo.runtime.trackers.files.threadstracking.config" in the runtime. This could be achieved by editing the "blacklist" file in your 'config' directory or using the @{link BlacklistComponent} annotation on your test class.

activate

public void activate(ComponentContext context)

Description copied from interface: Component

Activates the component.

This method is called by the runtime when a component is activated.

Specified by:

activate in interface Component

Overrides:

activate in class DefaultComponent

Parameters:

context - the runtime context

getApplicationStartedOrder

public int getApplicationStartedOrder()

Description copied from interface: Component

The component notification order for Component.applicationStarted(org.nuxeo.runtime.model.ComponentContext).

Components are notified in increasing order. Order 1000 is the default order for components that don't care. Order 100 is the repository initialization.

Specified by:

getApplicationStartedOrder in interface Component

Overrides:

getApplicationStartedOrder in class DefaultComponent

Returns:

the order, 1000 by default
