Examples of ucar.nc2.util.DiskCache2

ucar.nc2.util.DiskCache2
Manages a place on disk to persistently cache files, which are deleted when the last modified date exceeds a certain time. This starts up a thread to periodically scour itself; be sure to call exit() to terminate the thread.
Each DiskCache has a "root directory", which may be set as an absolute path, or reletive to the DiskCache "home directory". The root directory must be writeable. The DiskCache home directory is set in the following order:
1. through the system property "nj22.cachePersistRoot" if it exists
2. through the system property "user.home" if it exists
3. through the system property "user.dir" if it exists
4. to the current working directory
