Detailed Description

template<class Seq>
class xrpl::SeqEnforcer< Seq >

Enforce validation increasing sequence requirement.

Helper class for enforcing that a validation must be larger than all unexpired validation sequence numbers previously issued by the validator tracked by the instance of this class.

operator()()

template<class Seq>

bool xrpl::SeqEnforcer< Seq >::operator()	(	time_point	now,
		Seq	s,
		ValidationParms const &	p )

Try advancing the largest observed validation ledger sequence.

Try setting the largest validation sequence observed, but return false if it violates the invariant that a validation must be larger than all unexpired validation sequence numbers.

Parameters

now	The current time
s	The sequence number we want to validate
p	Validation parameters

Returns

Whether the validation satisfies the invariant
