Class ConfluenceVelocityResourceCache

java.lang.Object
  com.atlassian.confluence.util.ConfluenceVelocityResourceCache

All Implemented Interfaces:

org.apache.velocity.runtime.resource.ResourceCache

public class ConfluenceVelocityResourceCache
extends java.lang.Object
implements org.apache.velocity.runtime.resource.ResourceCache

Clearable velocity cache.

We configure velocity to use this cache, then we can get at the static methods to globally remove things from the cache if we need to. This is necessary for the dynamic decorator stuff.

Constructor Detail

ConfluenceVelocityResourceCache

public ConfluenceVelocityResourceCache(com.atlassian.cache.CacheFactory cacheFactory)

Create a resource cache using the provided cache manager. Everytime this is called, the resource cache singleton is replaced with the newly provided instance. There should only ever be one of these created but as we don't have control over the creating code (WebWork velcoity manager), we can't enforce singleton use via a factory method.

Method Detail

getInstance

public static ConfluenceVelocityResourceCache getInstance()

Get the Confluence resource cache singleton.

Returns:

Resource cache singleton, may be null if Confluence caching has not been initialised.

clearAllCaches

public static void clearAllCaches()

Deprecated. Use getInstance().clear()

Clear the contents of all caches that have been created so far

removeFromCaches

public static void removeFromCaches(java.lang.Object key)

Remove a particular object from the cache

Parameters:

key - the cache-key to remove. Any cached object with a key that has this key as a substring will be removed, for safety's sake.
