Public Functions Documentation

function TestEvent

inline explicit TestEvent(
    const Context * context
)

Parameters:

• context The event-tree walk context.

function interval

inline virtual Interval interval() override

Return: The domain interval for validation purposes only.

Reimplements: scram::mef::Expression::interval

function IsDeviate

inline virtual bool IsDeviate() override

Determines if the value of the expression contains deviate expressions.

Return:

• true if the expression's value deviates from its mean.
• false if the expression's value does not need sampling.

Warning: Improper registration of arguments may yield silent failure.

Reimplements: scram::mef::Expression::IsDeviate

The default logic is to check arguments with uncertainties for sampling. Derived expression classes must decide if they don't have arguments, or if they are random deviates.

Protected Attributes Documentation

variable context_

const Context & context_;

The evaluation context.
