-
generic_multiedge_match
(attr, default, op)[source]¶ Returns a comparison function for a generic attribute.
The value(s) of the attr(s) are compared using the specified operators. If all the attributes are equal, then the constructed function returns True. Potentially, the constructed edge_match function can be slow since it must verify that no isomorphism exists between the multiedges before it returns False.
- Parameters
attr (string | list) – The edge attribute to compare, or a list of node attributes to compare.
default (value | list) – The default value for the edge attribute, or a list of default values for the dgeattributes.
op (callable | list) – The operator to use when comparing attribute values, or a list of operators to use when comparing values for each attribute.
- Returns
match – The customized, generic
edge_match
function.- Return type
function
Examples
>>> from operator import eq >>> from networkx.algorithms.isomorphism.matchhelpers import close >>> from networkx.algorithms.isomorphism import generic_node_match >>> nm = generic_node_match("weight", 1.0, close) >>> nm = generic_node_match("color", "red", eq) >>> nm = generic_node_match(["weight", "color"], [1.0, "red"], [close, eq]) ...
