graph_tool

This is the core module providing the fundamental data structures and functions.

Fundamental classes

Graph	General multigraph class.
GraphView	A view of selected vertices or edges of another graph.
Vertex	Vertex descriptor.
Edge	Edge descriptor.

Property Maps

PropertyMap	This base class provides a mapping from vertices, edges or whole graphs to arbitrary properties.
VertexPropertyMap	This class provides a mapping from vertices to arbitrary properties.
EdgePropertyMap	This class provides a mapping from edges to arbitrary properties.
GraphPropertyMap	This class provides a mapping from graphs to arbitrary properties.
PropertyArray	This is a numpy.ndarray subclass which keeps a reference of its PropertyMap owner.
group_vector_property	Group list of properties props into a vector property map of the same type.
ungroup_vector_property	Ungroup vector property map vprop into a list of non-vector property maps.
map_property_values	Map the values of src_prop to tgt_prop according to the mapping function map_func.
infect_vertex_property	Propagate the prop values of vertices with value val to all their out-neighbors.
edge_endpoint_property	Return an edge property map corresponding to the vertex property prop of either the target and source of the edge, according to endpoint.
incident_edges_op	Return a vertex property map corresponding to a specific operation (sum, product, min or max) on the edge property eprop of incident edges on each vertex, following the direction given by direction.
perfect_prop_hash	Given a list of property maps props of the same type, a derived list of property maps with integral type htype is returned, where each value is replaced by a perfect (i.e. unique) hash value.
value_types	Return a list of possible properties value types.

Graph IO

load_graph	Load a graph from file_name (which can be either a string or a file-like object).
load_graph_from_csv	Load a graph from a csv file containing a list of edges and edge properties.

OpenMP configuration

openmp_enabled	Return True if OpenMP was enabled during compilation.
openmp_get_num_threads	Return the number of OpenMP threads.
openmp_set_num_threads	Set the number of OpenMP threads.
openmp_get_schedule	Return the runtime OpenMP schedule and chunk size.
openmp_set_schedule	Set the runtime OpenMP schedule and chunk size.
openmp_get_thresh	Return the minimum number of vertices necessary to enable parallelization.
openmp_set_thresh	Set the the minimum number of vertices necessary to enable parallelization.
