Enum Constant Detail

MANUAL

public static final CacheStrategy MANUAL

Deal with cached data manually. Call FileObject.refresh() to refresh the object data.

ON_RESOLVE

public static final CacheStrategy ON_RESOLVE

Refresh the data every time you request a file from FileSystemManager.resolveFile(java.lang.String).

ON_CALL

public static final CacheStrategy ON_CALL

Refresh the data every time you call a method on the fileObject. You'll use this only if you really need the latest info as this setting is a major performance loss.

Method Detail

values

public static CacheStrategy[] values()

for (CacheStrategy c : CacheStrategy.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf
