Detailed Description

Compact representation of the geometrical detector hierarchy.

Navigation through the compact view of the detector ...

Updated: Michael Case [ MEC ] 2010-02-11 A DDCompactView represents the detector as an acyclic directed multigraph. The nodes are instances of DDLogicalPart while the edges are pointers to DDPosData. Edges are directed from parent-node to child-node. Edges represented by DDPosData are the relative translation and rotation accompanied by a copy-number of the child-node towards the parent-node.

One node is explicitly marked as the root node. It is the DDLogicalPart which defines the base coordinate system for the detector. All subdetectors are directly or inderectly positioned inside the root-node.

Example:

The figureshows a compact-view graph consisting of 16 DDLogicalParts interconnected by 20 edges represented by pointers to DDPosData.

The compact-view also serves as base for calculating nodes in the expanded view. Paths through the compact-view can be viewed as nodes in the expanded-view (expansion of an acyclic directed multigraph into a tree). In the figure there are 5 different paths from CMS to Module2 (e.g. CMS-Pos1->Ecal-Pos4->EEndcap-Pos21->Module2) thus there will be 5 nodes of Module2 in the expanded view.

MEC: There has been a re-purposing of the DDCompactView to not only hold the representation described above (in detail this is the DDCompactViewImpl) but also own the memory of the stores refered to by the graph.

DDCompactView now owns the DDMaterial, DDSpecific, DDLogicalPart, DDRotation, DDSolid and etc. Removal of the global one-and-only stores, methods and details such as DDRoot will mean that all of these will be accessed via the DDCompactView.

Constructor & Destructor Documentation

DDCompactView::DDCompactView ( )

explicit

Creates a compact-view.

  : rep_(new DDCompactViewImpl),

DDCompactView::DDCompactView ( const DDLogicalPart &  rootnodedata )

explicit

EXPERIMENTAL! Creates a compact-view using a different root of the geometrical hierarchy

Compact-views can be created only after an appropriate geometrical hierarchy has been defined using DDpos().

Further it is assumed that the DDLogicalPart defining the root of the geometrical hierarchy has been defined using DDRootDef - singleton. It will be extracted from this singleton using DDRootDef::instance().root()!

The first time this constructor gets called, the internal graph representation is build up. Subsequent calls will return immidiately providing access to the already built up compact-view representation.

Currently the only usefull methods are DDCompactView::graph(), DDCompactView::root() !

const DDCompactView::Graph & DDCompactView::graph

(

)

const

Provides read-only access to the data structure of the compact-view.

The compact-view is kept in an acyclic directed multigraph represented by an instance of class Graph<DDLogicalPart, DDPosData*). Graph provides methods for navigating its content.
