Method Detail

writeTo

public void writeTo(WritableByteChannel channel,
                    @Nullable

             throws IOException

Description copied from interface: Serializer

Writes the serialized form of this object. The entire object may be written to the provided channel, or the object may be split over the provided channel and files added to the {@link FileSmoosher], where additional channels can be created via FileSmoosher.addWithSmooshedWriter(String, long). The latter approach is useful when the serialized form of the object is too large for a single smoosh container. At the time this javadoc was written, the max smoosh container size is limit to the max ByteBuffer size.
