Detailed Description

template<std::invocable F, typename R, typename... Os>
class live_cells::mutable_cell_view_base< F, R, Os >

A stateless mutable computed cell that does not cache its own value.

The value of the cell is computed whenever it is accessed and observers are added directly to the argument cells.

Warning: This is not a complete cell and hence does not satisfy the Cell concept. As such this class should not be instantiated directly. Instead the cell_view() function should be used to create stateless mutable computed cells.

Constructor & Destructor Documentation

template<std::invocable F, typename R , typename... Os>

live_cells::mutable_cell_view_base< F, R, Os >::mutable_cell_view_base	(	F	compute,
		R	reverse,
		Os...	args )

inline

Create a stateless mutable computed cell.

Parameters

compute	Compute value function. This function, of no arguments, should compute the cell's value as a function of the cells in args.
reverse	Reverse computation function. This function should set the values of the cells in args, such that compute returns the same value as the value that was assigned to the cell, which is passed to this function.
args	Argument cells referenced in compute

template<std::invocable F, typename R , typename... Os>

void live_cells::mutable_cell_view_base< F, R, Os >::value ( value_type value ) const

inline

Set the value of the cell.

Parameters

value The new value
