Inheritance diagram for fst4_cli::Criterion_Counting:

Public Types
typedef FST::Clonable_Impl< Criterion_Counting, CRITERION >	parent_impl

Public Member Functions
	Criterion_Counting (const std::shared_ptr< CRITERION > &inner, const std::shared_ptr< std::atomic< long long > > &count)
	Constructs the counting decorator around `inner`, sharing evaluation counts through `count`.
virtual bool	evaluate (RETURNTYPE &result, const PSubset sub) override
	counts the evaluation, then delegates to the wrapped criterion;
virtual std::ostream &	print (std::ostream &os) const override
	delegates to the wrapped criterion's print() – the decorator is invisible in listings
Public Member Functions inherited from FST::Clonable_Impl< Criterion_Counting, CRITERION >
CRITERION *	clone () const override
	dispatches to the DEEP_KIND mechanism (default CLONE_DEEP: Derived's copy-constructor)
CRITERION *	sharing_clone () const override
	dispatches to the SHARING_KIND mechanism (default CLONE_INHERIT: defers to Base, which throws by family convention)
CRITERION *	stateless_clone () const override
	dispatches to the STATELESS_KIND mechanism (default CLONE_INHERIT: defers to Base, which throws by family convention)

Private Member Functions
	Criterion_Counting (const Criterion_Counting &cc)
	deep-clones the wrapped criterion but SHARES the atomic evaluation counter across clones

Private Attributes
friend	parent_impl
std::shared_ptr< CRITERION >	_inner
	the wrapped criterion whose evaluate() calls are counted
std::shared_ptr< std::atomic< long long > >	_count
	evaluation counter, shared across clone()s (threaded-evaluator workers included)

Detailed Description

Criterion decorator counting evaluate() calls; the counter is shared by clone()s so evaluations performed by threaded-evaluator workers are included

Member Typedef Documentation
