throws java.io.IOException
- Throws:
java.io.IOException
scheduleRecursiveDeleteAfterShutdown
public static void scheduleRecursiveDeleteAfterShutdown(java.io.File fileOrDir)
- On some platforms, a file cannot be deleted while it is in use. In some cases,
certain files may be in use by the JVM until it exits, and therefore can only
be deleted after the JVM exits. Notably, this includes native library
files.
This method registers a shutdown hook that will spawn a separate JVM, from which
repeated attempts will be made to delete the specified file or directory. These
attempts will continue for up to 30 seconds, which should be enough time for this
JVM to exit, at which point any files it had open can be deleted.
execDeleteRecursively
public static void execDeleteRecursively(int numAttempts,
int millisBetweenAttempts,
java.io.File fileOrDir)
throws java.io.IOException
- Spawns a separate process that will delete the specified file or directory. The
process attempts the deletion repeatedly, until it succeeds, up to numAttempts
times.
- Throws:
java.io.IOException
deleteRecursively
public static boolean deleteRecursively(java.io.File fileOrDir)
copy
public static void copy(java.net.URL fromUrl,
java.io.File toFile)
throws java.io.IOException
- Throws:
java.io.IOException
