PlasmaCalcs.tools.properties.simple_property(internal_name, *, doc=None, default=NO_VALUE, setdefault=NO_VALUE, setdefaultvia=NO_VALUE, setable=True, delable=True, valid=UNSET, validate_from=UNSET, validate_default=False)

return a property with a setter and getter method for internal_name.

default: NO_VALUE or any object

if provided, getter uses this default if this attr has not been set.

setdefault: NO_VALUE or callable of 0 arguments

if provided, getter uses setdefault() if this attr has not been set.

(if internal_name is unset, getter sets self.{internal_name} = setdefault(),

then returns value at self.{internal_name}. Does not recalculate each time.)

E.g. setdefault = dict, creates a new dict.

(using default=dict() would share the dict amongst all instances;

using setdefault=dict creates a new dict for each instance when needed.)

setdefaultvia: NO_VALUE or str

if provided, getter uses self.{setdefaultvia}() if attr has not been set.

(if internal_name is unset, getter sets self.{internal_name} = self.{setdefaultvia}(),

then returns value at self.{internal_name}. Does not recalculate each time.)

E.g. setdefault = ‘_default_val’ –> getter calls & returns self._default_val(),

and remembers result, saving it to self.{internal_name}.

setable: bool

whether to allow this attribute to be set (i.e., define fset.)

delable: bool

whether to allow this attribute to be set (i.e., define fdel.)

valid: UNSET or iterable

if provided, only allow setting to values in valid.

validate_from: UNSET or str

if provided, get list of valid values from getattr(self, validate_from).

validate_default: bool

whether to apply validation to the results of setdefault() or setdefaultvia().

disabled by default, for efficiency.
