Instance Method Details

#add(*nodes_or_routes) ⇒ Object Also known as: route

Define nodes or routes(node-edge combinaitons). When an argument is a symbol, a node is defined.

add :a, :b

is equivalent to:

node :a
node :b

When an argument is a hash, edges are defined.

add :a => [:b, :c], :c => :d

is equivalent to:

edge :a_b
edge :a_c
edge :c_d

#edge(id, attrs = {}) ⇒ Object

Difine a edge or update a edge attributes. The first argument is ‘id` of the edge, which is a symbol or string constructed from two nodes joined with ’_’(underscore).

edge(:a_b, color:'red')

The corresponding nodes will be defined if these are not exist.

When ‘id` includes ’*‘(asterisk), multiple edges are updated.

add(:a => [:b, :c])
edge('a_*', arrowhead:'none')

is equivalent to:

edge(:a_b, arrowhead:'none')
edge(:a_c, arrowhead:'none')

You can draw two or more edges between a pair of nodes, by adding a identifier with a underscore after the edge id.

gv.edge(:a_b)
gv.edge(:a_b_1)

This create two nodes between a, b nodes.

You can define a endpoint to a node, by adding a point identifier with a colon after the each node. You must specify the identifiers in the label of the corresponding nodes.

gv.edge("a:x_b:y")
gv.node(:a, label:"<x> 1 | 2 | 3")
gv.node(:b, label:"4 | 5 |<y> 6")

The edge ‘a-b’ joins 1 of the node ‘a’ with 6 of the node ‘b’.
