Templates are used to match tuples in Rinda.
Alias for match.
 
               # File rinda/rinda.rb, line 169
def ===(tuple)
  match(tuple)
end
             
            Matches this template against tuple.  The tuple must be the same size as the template.  An element with a nil value in a template acts as a wildcard, matching any value in the corresponding position in the tuple.  Elements of the template match the tuple if the are #== or ===.
Template.new([:foo, 5]).match Tuple.new([:foo, 5]) # => true Template.new([:foo, nil]).match Tuple.new([:foo, 5]) # => true Template.new([String]).match Tuple.new(['hello']) # => true Template.new([:foo]).match Tuple.new([:foo, 5]) # => false Template.new([:foo, 6]).match Tuple.new([:foo, 5]) # => false Template.new([:foo, nil]).match Tuple.new([:foo]) # => false Template.new([:foo, 6]).match Tuple.new([:foo]) # => false
