Method Details

__init__(self)
(Constructor)

source code 

x.__init__(...) initializes x; see help(type(x)) for signature

Overrides: object.__init__
(inherited documentation)

has(self, edge)

source code 
Returns: bool
True if edge is in edge list

add(self, edge)

source code 

Add an edge to our internal representation. not multi-thread safe

Parameters:
  • edge (Edge) - edge to add

add_edges(self, start, dest, direction, label='')

source code 

Create Edge instances for args and add resulting edges to edge list. Convenience method to avoid repetitve logging, etc...

Parameters:
  • edge_list (EdgeList) - data structure to add edge to
  • start (str) - name of start node. If None, warning will be logged and add fails
  • dest (str) - name of start node. If None, warning will be logged and add fails
  • direction (str) - direction string (i/o/b)
Returns: bool
True if update occured

delete_all(self, node)

source code 

Delete all edges that start or end at node

Parameters:
  • node (str) - name of node
