Instance Method Summary collapse
-
#initialize(query) ⇒ QueryComplexity
constructor
State for the query complexity calculation: -
complexities_on_type
holds complexity scores for each type in an IRep node. -
#max_possible_complexity ⇒ Integer
-
#on_enter_field(node, parent, visitor) ⇒ Object
-
#on_leave_field(node, parent, visitor) ⇒ Object
-
#result ⇒ Object
Overide this method to use the complexity result.
