Examples of de.innovationgate.utils.TemporaryFile$EvictionTask

de.innovationgate.utils.TemporaryFile
A helper object to use temporary files that must have a special file name in file system. The object does not directly drop the temporary file in the temp folder but creates a parent directory with temporary name to drop it in there. Because of this the file may have any file name desired.
The file and directory will NOT be automatically deleted on VM termination anymore (see B000048C2). They should be manually deleted by calling {@link #delete()} when you are finished with them, or be bound to the eviction of a context object byusing {@link #deleteOnEviction(Object)}.
