Detailed Description
class live_cells::dynamic_compute_cell< F, State >
A computed cell which determines its argument cells at runtime.
This is a stateful cell that caches its value when computed and maintains its own observer set.
Constructor & Destructor Documentation
◆ dynamic_compute_cell() [1/2]
|
inline |
Create a dynamic computed cell with a given value computation function.
The function compute is called with no arguments to compute the value of the cell when necessary. It should reference its argument cells using the function call operator so that they are registered as dependencies of this cell.
- Parameters
-
compute Value computation function.
◆ dynamic_compute_cell() [2/2]

The function compute is called with no arguments to compute the value of the cell when necessary. It should reference its argument cells using the function call operator so that they are registered as dependencies of this cell.
- Parameters
-
key Key identifying cell. compute Value computation function.
