Detailed Description
template<typename T>
class fv::Reduce< T >
Reduce a Value of type vector<T> to just a T.
This is useful functionality to model, for instance, calculating the maximum element of a vector, or a the mean. See child classes for specific implementations.
Member Function Documentation
◆ update_value()
template<typename T >

inlineprivatevirtual |
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 >.
