definition of EntityView
Views are very widely used as an input to algorithms and the link between graphical objects and entities.
Views point to the same data as their corresponding handle classes. When modifying and entity, such as applying a coordinate transform to the atoms, these changes will also be reflected in the views.
The entity - chain -residue - atom hierarchy of the entity handles is replicated in the views, the most important difference being that not all atoms, residues and chains present in the entity must be present in the view. One can think of the views as a selection.
Views can be assembled in several different ways: To create a full view containing all the atoms, residues, chains and bonds of the entity, use EntityHandle::CreateFullView(), an empty view containing basically nothing is created with EntityHandle::CreateEmptyView().
Elements can be added with EntitView::AddAtom(), EntityView::AddResidue(), EntityView::AddChain(). The behaviour of these methods is influenced by a combination of ViewAddFlag. Note that none of the add methods insert bonds. Bonds can be added with EntityView::AddAllInclusiveBonds() or manually with EntityView::AddBond(). The elements can be removed with EntityView::RemoveChain(), EntityView::RemoveResidue() and EntityView::RemoveAtom().
A very convenient way to create views is with so-called Query query statements. The queries are executed via EntityHandle::Select() and EntityView::Select().
Two views can be combined by applying boolean operators such as Union(), Intersection() and Difference().

| ChainView AddChain | ( | const ChainHandle & | chain_handle, |

| ChainView AddChain | ( | const ChainView & | chain_view, |
| ViewAddFlags | flags = 0 |
||
| ) |
Add chain to view.
Same as AddChain(const ChainHandle&) but with the difference that only the residues or atoms included in the chain view are included when one of ViewAddFlag::INCLUDE_ATOMS or ViewAddFlag::INCLUDE_RESIDUES is set.
| chain_view | the handle that the view points to will be added to the view. |
| flags | can be a ORed together combination of ViewAddFlag |
| ResidueView AddResidue | ( | const ResidueHandle & | residue_handle, |
| ViewAddFlags | flags = 0 |
||
| ) |

If the residues's chain has not been added to the chain already, it will be added.
| residue_handle | is the residue to add |
| flags | can be a ORed together combination of ViewAddFlag |
| ResidueView AddResidue | ( | const ResidueView & | residue_view, |
| ViewAddFlags | flags = 0 |
||
| ) |
Add residue to view.
Same as AddReside(const ResidueHandle&, ViewAddFlags) but with the difference that only atoms included in the residue view are added when ViewAddFlag::INCLUDE_ATOMS is set.
