All Implemented Interfaces:

Encoder<Resource<Bitmap>>, ResourceEncoder<Bitmap>

public class BitmapEncoder

Method Detail

encode

public boolean encode(Resource<Bitmap> resource,
             OutputStream os)

Description copied from interface: Encoder

Writes the given data to the given output stream and returns True if the write completed successfully and should be committed.

Specified by:

encode in interface Encoder<Resource<Bitmap>>

Parameters:

resource - The data to write.

os - The OutputStream to write the data to.

getId

public String getId()

Description copied from interface: Encoder

Returns an ID identifying any transformation this encoder may apply to the given data that will be mixed in to the cache key.

If the encoder does not transform the data in a way that significantly affects the cached result (ie performs no unusual compression or downsampling) an empty string is an appropriate id.

Specified by:

getId in interface Encoder<Resource<Bitmap>>
