utility::DenseBoolMap< NUM_ELEMS, BASE_INDEX > Struct Template Reference

This struct condenses N boolean values into roughly N bits, saving roughly 4x memory. NUM_ELEMS parameter takes in the number of boolean values. BASE_INDEX parameter takes in the index of the first value. The recommended way to use this struct is with an enum. See core::scoring::hbonds::graph::AtomInfo for an example. More...

Detailed Description

template<unsigned int NUM_ELEMS, unsigned int BASE_INDEX>
struct utility::DenseBoolMap< NUM_ELEMS, BASE_INDEX >

This struct condenses N boolean values into roughly N bits, saving roughly 4x memory. NUM_ELEMS parameter takes in the number of boolean values. BASE_INDEX parameter takes in the index of the first value. The recommended way to use this struct is with an enum. See core::scoring::hbonds::graph::AtomInfo for an example.
