Method Details

get

@Nullable
File get(Key key)

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.

Parameters:

key - The key in the cache.

Returns:

An InputStream representing the data at key at the time get is called.

put

void put(Key key,
 DiskCache.Writer writer)

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).

Parameters:

key - The key to write to.

writer - An interface that will write data given an OutputStream for the key.

delete

void delete(Key key)

Remove the key and value from the cache.

Parameters:

key - The key to remove.

clear

void clear()

Clear the cache.
