This is an undirected edge representation.
Creates a new Edge with the params Hash providing settings for all edge options. The option_list parameter restricts those options to the list of valid names it contains.
# File lib/rgl/rdot.rb, line 401 def initialize (params = {}, option_list = EDGE_OPTS) super(params, option_list) @from = params['from'] ? params['from'] : nil @to = params['to'] ? params['to'] : nil end
Returns a string representation of this edge which is consumable by the graphviz tools dot and neato. The leader parameter is used to indent every line of the returned string, and the indent parameter is used to additionally indent nested items.
# File lib/rgl/rdot.rb, line 411 def to_s (leader = '', indent = ' ') stringified_options = @options.collect do |name, val| unless val.nil? then leader + indent + "#{quote_ID(name)} = #{quote_ID(val)}" end end.compact.join( ",\n" ) f_s = @from || '' t_s = @to || '' if stringified_options.empty? then leader + quote_ID(f_s) + ' ' + edge_link + ' ' + quote_ID(t_s) else leader + quote_ID(f_s) + ' ' + edge_link + ' ' + quote_ID(t_s) + " [\n" + stringified_options + "\n" + leader + "]" end end
