Method Detail

checksum_impl

protected long checksum_impl()

Description copied from class: Keyed

High-quality 64-bit checksum of the content of the object. Similar to hashcode(), but a long to reduce the chance of hash clashes. For composite objects this should be defined using the subcomponents' checksums (or hashcodes if not available). If two Keyed objects have the same checksum() there should be a 1 - 1/2^64 chance that they are the same object by value.
