Member Function Documentation

is_cached()

template<typename DomainValue, typename ComparatorT = decltype(std::equal_to<DomainValue>())>

bool8_t autoware::common::optimization::CacheStateMachine< DomainValue, ComparatorT >::is_cached ( const DomainValue &  x, const ExpressionTerm &  term  ) const

inlinenoexcept

Check if the term is already evaluated and cached for a given parameter

Parameters

x	Parameter value
term	Expression term to query the cache status. Can be one of the following: SCORE, JACOBIAN, HESSIAN

Returns

True if the result for this term with the given parameter matches the previous state and is already cached.

update()

template<typename DomainValue, typename ComparatorT = decltype(std::equal_to<DomainValue>())>

void autoware::common::optimization::CacheStateMachine< DomainValue, ComparatorT >::update ( const DomainValue &  value, const ComputeMode &  mode  )

inlinenoexcept

Update the state with the given parameter and the computation mode/

Parameters

value	Parameter value used in computation
mode	Computation mode
