biomol.core.View

class View(mol, indices)

Bases: Generic[A_co, R_co, C_co, M_co]

Base class for all views.

This class defines the common interface for all views, including methods for converting between different structural levels, accessing features, and performing set operations.

Parameters:

• mol (BioMol) – The parent molecule.

• indices (NDArray[np.integer]) – The indices of the elements in the view.

Attributes

atoms	View of the atoms in the selection.
chains	View of the chains in the selection.
indices	Return the indices of the view.
level	The structural level of the view.
mol	Return the parent molecule.
residues	View of the residues in the selection.
unique_indices	Return the unique indices of the view, preserving first-occurrence order.

Methods

extract	Extract a new BioMol cropped to the current view.
get_container	Return the feature container cropped to the view's indices.
get_feature	Return the feature for the given key, cropped to the view's indices.
is_empty	Return True if the view is empty (contains no elements).
is_subset	Return True if the view is a subset of another view.
new	Return a new view with the specified indices.
select	Return a new view filtered by feature values.
sort	Return a new view with sorted indices.
to_atoms	Return an AtomView of the atoms in the selection.
to_chains	Return a ChainView of the chains in the selection.
to_residues	Return a ResidueView of the residues in the selection.
unique	Return a new view with unique indices, preserving first-occurrence order.
with_features	Modify features in the current view and return an updated BioMol.
