Class xlifepp::GeoNode

class GeoNode

utility class to describe a hierarchical composite construction each node represent either a unary operation on a geometry/GeoNode or a binary operation on two geometries/GeoNodes op(g1) op(g1,g2) its main purpose is to describe as a tree some complex composite geometries involving several minus, plus, common operations the GeoNode will be attached to any geometry as a member data (not allocated for canonical geometries) GeoNode may be used in two way, either handling GeoNode(s) or Geometry(s) (terminal leaf) in a compact construction such as (g1+g2+g3)-g4 the representation will be: geonode(-, &geonode(+, &geonode(+&g1,&g2) ,&g3), &g4) (two additional GeoNodes) if g=g1+g2+g3 has been already constructed, the representation will be geonode(-, &g, &g4) (no additional GeoNode !) in other words as soon as a geometry pointer is available it is used instead of a new geo node all the tree may be unrolled using expand() function

Public Functions

GeoNode(const GeoNode &gn)

copy constructor (no deep copy of geometry pointers, see updateGeo)

copy constructor, no deep copy of geometry pointers

~GeoNode()

destructor, geometry pointeurs are not deleted

increment by one level_ of each node from current node level

string_t asString() const

string representation of GeoNode

interpret node as a string for printing purpose

void expand()

expand recursively geometry pointers having themselves GeoNode representations

recursive expansion of a GeoNode (substitute geometry pointers by its Geonode if exists)

GeoNode &operator=(const GeoNode &gn)

assign operator (no deep copy of geometry pointers, see updateGeo)

assign operator, no deep copy of geometry pointers

void updateGeo(std::map<Geometry*, Geometry*> &newgeo)

update Geometry pointers from a map of Geometry* moves

recursive update of geometry pointers using the map relating old to new geometry pointers be cautious as copy or assignment does not realize a deep copy of geometry pointers to maintain integrity, they have probably to be updated after a copy or an assign operation

void updateLevel(number_t l)

increment by one level_ of each node from current node
