networkx.utils.not_implemented_for¶

networkx.utils.not_implemented_for(*graph_types)[source]¶

Decorator to mark algorithms as not implemented

Parameters:	graph_types : container of strings Entries must be one of ‘directed’,’undirected’, ‘multigraph’, ‘graph’.
Returns:	_require : function The decorated function.
Raises:	NetworkXNotImplemnted If any of the packages cannot be imported

Notes

Multiple types are joined logically with “and”. For “or” use multiple @not_implemented_for() lines.

Examples

Decorate functions like this:

@not_implemnted_for('directed')
def sp_function(G):
    pass

@not_implemnted_for('directed','multigraph')
def sp_np_function(G):
    pass
