writeTo
Description copied from interface:SerializerWrites 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 thewhere additional channels can be created viainvalid @link
{@link FileSmoosher],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 maxByteBuffersize.- Specified by:
