ScienceState

class astropy.utils.state.ScienceState

Bases: object

Science state subclasses are used to manage global items that can affect science results. Subclasses will generally override validate to convert from any of the acceptable inputs (such as strings) to the appropriate internal objects, and set an initial value to the _value member so it has a default.

Examples

class MyState(ScienceState):
    @classmethod
    def validate(cls, value):
        if value not in ('A', 'B', 'C'):
            raise ValueError("Must be one of A, B, C")
        return value

Methods Summary

get()	Get the current science state value.
set(value)	Set the current science state value.
