Graph Queries

(binary? graph )

Returns #t if graph is not a hypergraph.

(multigraph? graph )

Returns #t if graph is of a type allowing multiple edges.

(<mbingraph>? graph* )
(<mubingraph>? graph* ) (<mdbingraph>? graph* )
(<mhypergraph>? graph* ) (<muhypergraph>? graph* )
(<mdhypergraph>? graph* ) (<bingraph>? graph* )
(<ubingraph>? graph* ) (<dbingraph>? graph* )
(<hypergraph>? graph* ) (<uhypergraph>? graph* )
(<dhypergraph>? graph* )

Returns #t if graph is of the appropriate type.
