Constructor & Destructor Documentation

constant_cell()

template<typename T >

live_cells::constant_cell< T >::constant_cell ( const T & value )

inline

Parameters

value

The constant value.

All constant_cell's with the same value have the same key.

Returns

The key.

operator()()

template<typename T >

T live_cells::constant_cell< T >::operator() ( ) const

inline

Get the constant value held by this cell.

Note

This cell is not tracked as a dependency since its value never changes.

Returns

The constant value.

value()

template<typename T >

T live_cells::constant_cell< T >::value ( ) const

inline
