Detailed Description

template<typename T>
class fv::BoundValue< T >

A generic value owning only a function object.

All necessary values upon which this value depends must be bound to the function object.

◆ update_value()

template<typename T >
void fv::BoundValue< T >::update_value ( )
inlineprotectedvirtual

Updates the internal value.

This function should be overridden by any child class to do the actual work of updating value based on whatever rules the class chooses. Normally, this consists of geting the values from some associated Value objects, doing some calculation on them, and storing the result in value.

Implements fv::DerivedValue< T >.
