FluidSpecialValueSpecifier

class PlasmaCalcs.dimensions.fluids.FluidSpecialValueSpecifier(getter, name=None, *args_super, iseler=None, **kw_super)

class to specify special values for FluidDimension.

E.g. fluids.get(ELECTRON) is equivalent to fluids.get_electron().

E.g. (fluid_dim.v = IONS) is equivalent to (fluid_dim.v = fluid_dim.values.get_electron())

getter: str: self specifies to use the value(s): fluids.{getter}().
name: str: name of this object; will only be used in repr.
iseler: None or str: self specifies to use (during xarray_isel or xarray_sel) indexes: fluids.{iseler}()

additional args & kw go to Sentinel.__new__

Methods

`_getter_as_str`()	returns str representation of self.getter.
`_getter_from_str`(dlist)	get the value from dlist specified by str self.getter.
`_iseler_as_str`()	returns str representation of self.iseler.
`_iseler_from_str`(dvals)	get the indexes from dlist specified by str self.iseler.
`_iseler_when_none`(dvals)	crash, because self was passed to xarray_isel or xarray_sel but self.iseler is None.
`_repr_contents`()	contents for repr; used by __repr__.

_getter_as_str(): returns str representation of self.getter.

Use self.init_getter if it exists, else self.getter if it exists, else ‘UNKNOWN_GETTER’.

_getter_from_str(dlist): get the value from dlist specified by str self.getter.

_iseler_as_str(): returns str representation of self.iseler.

Use self.init_iseler if it exists, else self.iseler if it exists, else ‘UNKNOWN_ISELER’.

_iseler_from_str(dvals): get the indexes from dlist specified by str self.iseler.

_iseler_when_none(dvals): crash, because self was passed to xarray_isel or xarray_sel but self.iseler is None.
