Property maps
Boost.Graph makes extensive use of property maps. We define a few maps which use the particle attributes to store their data. Each map is constructed by passing an appropriate attribute key, to specify the attribute used to store the data. Attempt to store to an attribute which the particle does not already have adds the attribute to the particle. More information about property maps can be found in the Boost.PropertyMap documentation.
	VertexFloatPropertyMap
	Provide boost access to a Float attribute each vertex.
	VertexIntPropertyMap
	Provide boost access to an Int attribute each vertex.
	VertexVertexPropertyMap
	Provide boost access to a kernel::Particle attribute each vertex. More...
	EdgeFloatPropertyMap
	Provide boost access to a Float attribute on the edges such as length.
	EdgeIntPropertyMap
	Provide boost access to an Int attribute on each edge.

Detailed Description

The BondGraph class implements the following boost graph concepts

• bidirectional_graph
• adjacency_graph
• vertex_list_graph
• edge_list_graph.

See the Boost.Graph manual for more details and a list of algorithms.

The vertices are Bondeds. The type of the edge_descriptors is internal. You can use the get_bond() method to get the corresponding Bond.

And all vertices can be assumed to have internal boost vertex indices. The Boost.PropertyMap to access these can be accessed using the get_vertex_index_map() function.

Some usage examples

    boost::isomorphism(a,b,
        boost::isomorphism_map(BondGraph::VertexVertexPropertyMap(pk))
        .vertex_index1_map(a.get_vertex_index_map())
        .vertex_index2_map(b.get_vertex_index_map()));
boost::dijkstra_shortest_paths(a, Bonded(),
 boost::predecessor_map(BondGraph::VertexVertexPropertyMap(pk))
 .weight_map(BondGraph::EdgeFloatPropertyMap(Bond::get_legnth_key()))
 .distance_map(BondGraph::VertexFloatPropertyMap(FloatKey("graph distance")))
 .vertex_index_map(a.get_vertex_index_map()));

)

All the leaves will be made Bonded particles if they are not already.

Note

The hierarchy must not have any bonds to particles not in the hierarchy.
