Method Detail

get

public static DiskCache get(File directory,
                            int maxSize)

Returns:

The new disk cache with the given arguments, or the current cache if one already exists

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:

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)
