Template Class GlobalTradeSequence¶

Class Documentation¶

template<typename Hash>
class GlobalTradeSequence¶

Handles a sequence of num_global_trades hash functions each with its own set of parameters. It prominently exposes the “current” hash function and its successors. Switching the current hash function is possible with using the switch_to_round method.

hash, invert access the “current” hash function hash_next accesses the successor of “current” which is the identity if there are no further hash functions

Template Parameters:

Default – constructable, copy-able, requires methods sample_parameters, set_as_identity, hash and (optinally) invert
