Detailed Description

template<typename Base>
class live_cells::changes_only_cell_state< Base >

Mixin that modifies a compute_cell_state subclass to only notify its observers if the new value of the cell is not equal (!=) to the previous value.

Base is a compute_cell_state subclass, which this class inherits.

Note

This mixin converts the evaluation semantics of the cell from lazy, computed only when the value is actually referenced, to eager, computed whenever the value of an argument cell changes.
