Inherits IntEnum.
Static Public Attributes | |
| int | UNSET = 0 |
| Selects an unconfigured, non-runnable state. | |
| int | P1 = 1 |
| Selects conventional translational periodicity. | |
| int | P21 = 2 |
| Selects P2_1 screw-symmetry periodicity. | |
Identifies a periodic-boundary configuration value.
UNSET is an invalid, non-runnable sentinel. It does not select an aperiodic system and is rejected by the public periodic-boundary setters. P1 selects conventional three-dimensional translational periodicity. P21 selects the P2_1 screw-symmetry condition.
Integer values 0, 1, and 2 can be converted to this enumeration.
