juce::SmoothedValueBase< SmoothedValueType > Class Template Reference

Detailed Description

template<typename SmoothedValueType>
class juce::SmoothedValueBase< SmoothedValueType >

A base class for the smoothed value classes.

This class is used to provide common functionality to the SmoothedValue and dsp::LogRampedValue classes.
