A view presenting any cell backend as a NumericCell (the plain-numpy presentation).

Classes¶

CellNumericView

A view presenting an underlying cell backend as a NumericCell.

Module Contents¶

class httk.atomistic.models.cell.numeric_view.CellNumericView(obj, **hints)[source]¶

Bases: httk.atomistic.models.cell.view_base.CellViewBase, httk.atomistic.models.cell.numeric.NumericCell

A view presenting an underlying cell backend as a NumericCell.

This view is a genuine NumericCell, so it can be passed anywhere one is accepted. Its exact Cell is built lazily from the backend on first access, preserving the scale/unscaled split. Like a NumericCell it requires numpy (raising ImportError otherwise).

Parameters:

obj (httk.atomistic.models.cell.like.CellLike) – The cell-like object to present.
**hints (Any) – Backend-selection hints.

unwrap()[source]¶

Return the raw object behind the backend.

Returns:: The unwrapped source object.
Return type:: Any

unview()[source]¶

Return this presentation as a standalone numeric cell.

Returns:: The plain-numpy presentation.
Return type:: httk.atomistic.models.cell.numeric.NumericCell
