Class QuickResourceManagerImpl

java.lang.Object
  org.apache.velocity.runtime.resource.ResourceManagerImpl
      no.sesat.search.view.velocity.QuickResourceManagerImpl

All Implemented Interfaces:

org.apache.velocity.runtime.resource.ResourceManager

public final class QuickResourceManagerImpl
extends org.apache.velocity.runtime.resource.ResourceManagerImpl

A quicker replacement for ResourceManagerImpl that avoids doing resource loading and parsing while holding a global exclusive lock. This implementation creates new resource instances instead of updating existing ones and loads and parses them in the background. This removes the need for locking and the only synchronization done is whatever synchronization measures the cache is taking. Resources not yet in the cache are loaded synchronously. The reduced locking is achieved at the expense of resources possibly getting loaded several times during startup or reload.
