Class Method Summary

• .===(element) ⇒ Object

  :call-seq: new(type, hash = {}) new(type, yaml = {}) new(type, pg_conn = nil).

Class Method Details

.===(element) ⇒ Object

Make the Data module pretend to have Database object instances

# File 'lib/pg_graph.rb', line 107

def self.===(element) element.is_a?(PgGraph::Data::Connection) or super end

.new(type, arg) ⇒ Object

:call-seq:

new(type, hash = {})
new(type, yaml = {})
new(type, pg_conn = nil)

Note that together with ::=== and Data::Database#is_a? this makes Data::Database pretend it is an instance of the Data module

# File 'lib/pg_graph.rb', line 100

def self.new(type, arg)
  constrain type, PgGraph::Type
  constrain arg, Hash, PgConn, NilClass
  Database.new(type, arg)
