  • Method Details

    • get

      @Deprecated public static DiskCache get(File directory, long maxSize)
      Deprecated.
      Use create(File, long) to create a new cache with the specified arguments.
      Get a DiskCache in the given directory and size. If a disk cache has already been created with a different directory and/or size, it will be returned instead and the new arguments will be ignored.
      Parameters:
      directory - The directory for the disk cache
      maxSize - The max size for the disk cache
      Returns:
      The new disk cache with the given arguments, or the current cache if one already exists

    • create

      public static DiskCache create(File directory, long maxSize)
      Create a new DiskCache in the given directory with a specified max size.
      Parameters:
      directory - The directory for the disk cache
      maxSize - The max size for the disk cache
      Returns:
      The new disk cache with the given arguments

    • get

      public 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

      public void put(Key key, 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.
      writer - An interface that will write data given an OutputStream for the key.

    • delete

      public void delete(Key key)
      Description copied from interface: DiskCache
      Remove the key and value from the cache.
      Specified by:
      delete in interface DiskCache
      Parameters:
      key - The key to remove.

    • clear

      public void clear()
      Description copied from interface: DiskCache
      Clear the cache.
