cellcomplex.graph.interface.property_graph module

This module provide a set of concepts to add properties to graph elements

class cellcomplex.graph.interface.property_graph.IPropertyGraph

Bases: object

Directed graph with properties associated with edges and vertices. Properties may not be defined on all elements. Properties may be empty on some elements. A property is a map between an element id (vid or eid) and a data.

add_edge_property(property_name)

add a new map between eid and a data do not fill this property for any edge

add_vertex_property(property_name)

add a new map between vid and a data do not fill this property for any vertex

edge_property(property_name)

return a map between eid and data for all edges where property_name is defined

Return type

dict of {eid:data}

edge_property_names()

iter on names of all property maps defined on edge return iter of keys

graph_property()

return a dict containing the graph properties/

Return type

dict of {property_name:data}

remove_edge_property(property_name)

remove the map called property_name from the graph

remove_vertex_property(property_name)

remove the map called property_name from the graph

vertex_property(property_name)

return a map between vid and data for all vertices where property_name is defined

Return type

dict of {vid:data}

vertex_property_names()

iter on names of all property maps defined on vertices return iter of keys

exception cellcomplex.graph.interface.property_graph.PropertyError

Bases: Exception
