Method Detail

prepareCache

public static void prepareCache()

Called from Main.run early in the startup sequence to indicate that available files should be cached from now on. Should be matched by a call to discardCache() since the cache will be invalid if the user e.g. installs a new NBM without restarting.

discardCache

public static void discardCache()

Called after startup is essentially complete. After this point, the list of files in the installation are not cached, since they might change due to dynamic NBM installation. Anyway the heaviest uses of InstalledFileLocator are during startup so that is when the cache has the most effect. XXX called somewhat too late, before all libraries are initialized. Better might be to wait until a few seconds have passed since the last call. Or check for changes in .lastModified files since these should change if any NBM activity happens.

locate

public File locate(String relativePath,
                   String codeNameBase,
                   boolean localized)

Searches user dir and install dir(s).

Specified by:

locateAll

public Set<File> locateAll(String relativePath,
                           String codeNameBase,
                           boolean localized)
