BioSimSpace.Gateway.Length¶

class BioSimSpace.Gateway.Length(help=None, default=None, unit=None, minimum=None, maximum=None, allowed=None)[source]¶

A length requirement.

Examples

Create a length requirement with a default of 10 Angstrom.

>>> import BioSimSpace as BSS
>>> my_length = BSS.Gateway.Length(help="A length requirement", default=10, unit="angstrom")

The same, but explicitly passing a Length for the default.

>>> import BioSimSpace as BSS
>>> my_length = BSS.Gateway.Length(help="A length requirement",
...                                default=10*BSS.Units.Length.angstrom)

Create a length requirement with a default of 10 Angstrom and a maximum of 50 nanometers. Note that the unit is taken from the default value.

>>> import BioSimSpace as BSS
>>> my_length = BSS.Gateway.Length(help="A length requirement",
...                                default=10*BSS.Units.Length.angstrom,
...                                maximum=50*BSS.Units.Length.nanometer)
