Detailed Description

template<class T>
struct Cantera::CachedValue< T >

A cached property value and the state at which it was evaluated

This struct stores the value of some property evaluated at a particular thermodynamic state. The value can be either a real scalar or an array, depending on the template parameter T. The exact meaning of state1, state2, and stateNum is determined by the function using the cached value, which can check any combination of these variables before deciding whether to recompute the cached values.

References to CachedValue objects are returned by the "get" methods of ValueCache, e.g. ValueCache::getScalar. Functions accessing cached values should use the typedefs CachedScalar and CachedArray. See ValueCache for details on how these classes should be used together.

bool validate ( double state1New )

inline

Check whether the currently cached value is valid based on a single state variable.

If it is not valid it updates the stored state to the new state in addition to returning false.

double state1

Value of the first state variable for the state at which value was evaluated, e.g.

temperature.

density or pressure.

int stateNum

A surrogate for the composition.

For cached properties of Phase, this should be set to Phase::stateMFNumber()
