-/**
- * A cache that uses a bounded amount of space on a filesystem. Each cache
- * entry has a string key and a fixed number of values. Each key must match
- * the regex <strong>[a-z0-9_-]{1,120}</strong>. Values are byte sequences,
- * accessible as streams or files. Each value must be between {@code 0} and
- * {@code Integer.MAX_VALUE} bytes in length.
- *
- * <p>The cache stores its data in a directory on the filesystem. This
- * directory must be exclusive to the cache; the cache may delete or overwrite
- * files from its directory. It is an error for multiple processes to use the
- * same cache directory at the same time.
- *
- * <p>This cache limits the number of bytes that it will store on the
- * filesystem. When the number of stored bytes exceeds the limit, the cache will
- * remove entries in the background until the limit is satisfied. The limit is
- * not strict: the cache may temporarily exceed it while waiting for files to be
- * deleted. The limit does not include filesystem overhead or the cache
- * journal so space-sensitive applications should set a conservative limit.
- *
- * <p>Clients call {@link #edit} to create or update the values of an entry. An
- * entry may have only one editor at one time; if a value is not available to be
- * edited then {@link #edit} will return null.
- * <ul>
- * <li>When an entry is being <strong>created</strong> it is necessary to
- * supply a full set of values; the empty value should be used as a
- * placeholder if necessary.
- * <li>When an entry is being <strong>edited</strong>, it is not necessary
- * to supply data for every value; values default to their previous
- * value.
- * </ul>
- * Every {@link #edit} call must be matched by a call to {@link Editor#commit}
- * or {@link Editor#abort}. Committing is atomic: a read observes the full set
- * of values as they were before or after the commit, but never a mix of values.
- *
- * <p>Clients call {@link #get} to read a snapshot of an entry. The read will
- * observe the value at the time that {@link #get} was called. Updates and
- * removals after the call do not impact ongoing reads.
- *
- * <p>This class is tolerant of some I/O errors. If files are missing from the
- * filesystem, the corresponding entries will be dropped from the cache. If
- * an error occurs while writing a cache value, the edit will fail silently.
- * Callers should handle other problems by catching {@code IOException} and
- * responding appropriately.
