| net.refractions.udig.project.IResourceCachingInterceptor
All known Subclasses: net.refractions.udig.project.internal.interceptor.ResourceCacheInterceptor,
| IResourceCachingInterceptor | | public interface IResourceCachingInterceptor (Code) | | Controls the caching of resources returned by:
ILayer.getResource(Classorg.eclipse.core.runtime.IProgressMonitor) .
Example:
If a new feature store was returned each time then every plugin that is interested in
events would need to create a resource interceptor and every request for a FeatureStore
would result in both a new FeatureStore and a new listener for every interested plugin.
Since the Datastore's Listener manager often keeps the listeners indefinately then we
would very quickly have 10s to 100s of listeners that can't be garbage collected and
possibly featurestores as well.
The "active" caching strategy is stored in the
ProjectPlugin.getPlugin().getPreferenceStore().getString( "P_LAYER_RESOURCE_CACHING_STRATEGY" ).
Set the preference to activate a custom Caching strategy.
