Start tracking the resource (or return the last modified time of an already tracked resource). Only file system resources are tracked. Resources are tracked until any resource changes, at which points listeners are notified and the internal state is cleared.- Specified by:
trackResource
in interfaceResourceChangeTracker
- Parameters:
resource
- to track- Returns:
- last modified time, to nearest second

addDependency
Description copied from interface:ResourceDependencies
Marks the dependency as an additional resource. A change to the dependency is considered the same as a change to the resource being transformed.- Specified by:
addDependency
in interfaceResourceDependencies
-
forceInvalidationEvent
Description copied from interface:ResourceChangeTracker
Forces an invalidation event. This is required in a rare case, to clear out aStreamableResource
generated from the component message catalog; there are some walls in place that prevent the message catalog's underlyingResource
s from being exposed.- Specified by:
forceInvalidationEvent
in interfaceResourceChangeTracker

-
checkForUpdates
Description copied from interface:UpdateListener
Invoked to force the receiver to check for updates to whatever underlying resources it makes use of.- Specified by:
checkForUpdates
in interfaceUpdateListener
-
setCurrentClassName
Description copied from interface:ResourceChangeTracker
Informs this service that the resources being loaded are associated with a given Tapestry component (i.e. component, page, mixin and base) component class.- Specified by:
setCurrentClassName
in interfaceResourceChangeTracker
- Parameters:
className
- The fully classified class name of the component or page associated with the current resources being processed.
-
clearCurrentClassName
Description copied from interface:ResourceChangeTracker
Informs this service that no component class is associated with the resources being loaded.- Specified by:
