      • get

        public java.io.File get​(Key key)
        Description copied from interface: DiskCache
        Get the cache for the value at the given key.

        Note - This is potentially dangerous, someone may write a new value to the file at any point in time and we won't know about it.

        Specified by:
        get in interface DiskCache
        Parameters:
        key - The key in the cache.
        Returns:
        An InputStream representing the data at key at the time get is called.

      • put

                DiskCache.Writer writer)
        Description copied from interface: DiskCache
        Write to a key in the cache. DiskCache.Writer is used so that the cache implementation can perform actions after the write finishes, like commit (via atomic file rename).
        Specified by:
        put in interface DiskCache
        Parameters:
        key - The key to write to.
