Each cache + * entry has a string key and a fixed number of values. Each key must match + * the regex [a-z0-9_-]{1,120}. Values are byte sequences, + * accessible as streams or files. Each value must be between {@code 0} and + * {@code Integer.MAX_VALUE} bytes in length. + * + *

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. + * + *

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. + * + *

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. + *

    + *
  • When an entry is being created it is necessary to + * supply a full set of values; the empty value should be used as a + * placeholder if necessary. + *
  • When an entry is being edited, it is not necessary + * to supply data for every value; values default to their previous + * value. + *
+ * 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. + * + *

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. + * + *

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. + */ +public final class DiskLruCache implements Closeable { + static final String JOURNAL_FILE = "journal"; + static final String JOURNAL_FILE_TEMP = "journal.tmp"; + static final String JOURNAL_FILE_BACKUP = "journal.bkp"; + static final String MAGIC = "libcore.io.DiskLruCache"; + static final String VERSION_1 = "1"; + static final long ANY_SEQUENCE_NUMBER = -1; + private static final String CLEAN = "CLEAN"; + private static final String DIRTY = "DIRTY"; + private static final String REMOVE = "REMOVE"; + private static final String READ = "READ"; + + /* + * This cache uses a journal file named "journal".
