Playing with Pacer

works.rb

#!`which jruby`

require 'rubygems'
require 'pacer'

graph = Pacer.tg
graph.import("/tmp/enron_summary.xml")

# Focus on one email address, that of Tim Belden
sender = graph.v.filter(:address => 'louise.kitchen@enron.com')

# Check the vertex's properties
sender.inspect

# Look into the volume of emails Tim sent to each address
out_edges = sender.out_e
out_edges.each {|e| vs = e.in_v; vs.each {|v| puts "#{v[:address]} = #{e[:volume]}" } }

instead of graph.v.filter(:address => ...), just use graph.v(:address => ...) because that way it will use indices if possible and be considerably faster.

You could change the last line to the following:

out_edges.as(:var_name).in_v.each_context { |v| puts "#{ v[:address]} = #{ v.vars[:var_name][:volume] }" }

To get the first result from any route, just use route.first. If you wanted to get the fifth element, you can use route[4].first
