Instance Method Details

#printed?(value = nil) ⇒ Boolean

DSL accessor for the printed flag. Returns true if this object hasn’t been printed to the screen yet.

It’s just a useful flag when building a report (e.g., you can set printed? to true everytime you touch an object, and then you’ll know if you’ve printed a group already.)

Example:

printed?
# => false

printed? true
# => true

printed?
# => true

Returns:

  • (Boolean)

def printed?(value=nil)
  if value
    @printed = value
  else
    @printed ||= false
  end
end

#qualification(hash) ⇒ Object

Redefines the qualifies? test for this object

Example:

# By default, qualifies? always returns true.

qualifies? :a => 1
# => true

# But if we set it...
qualification :a => 2

# Then qualifies? returns false unless :a == 1
qualifies? :a => 1
# => false

qualifies? :a => 2
# => true

  # Performance hack: improves overall benchmark from 1.37 to 0.96 by rendering the key and value inline.
  #                   Don't use any weird keys or values.  Stick to standard ruby library ones unless you know what you're doing.
  instance_eval %{
    def qualifies?(i)
      i[#{@key.inspect}] == #{@value.inspect}
    end
  }
end

#qualifies?(record) ⇒ Boolean

This will always return true until set by qualification.

Returns:

  • (Boolean)
