Class: GraphQL::Analysis::QueryComplexity::TypeComplexity
- Inherits:
-
Object
- Object
- GraphQL::Analysis::QueryComplexity::TypeComplexity
- Defined in:
- lib/graphql/analysis/query_complexity.rb
Overview
Selections on an object may apply differently depending on what is actually returned by the resolve function. Find the maximum possible complexity among those combinations.
Instance Method Summary collapse
-
#initialize ⇒ TypeComplexity
constructor
A new instance of TypeComplexity.
-
#max_possible_complexity ⇒ Object
Return the max possible complexity for types in this selection.
-
#merge(type_defn, complexity) ⇒ Object
Store the complexity for the branch on
type_defn
.
Constructor Details

Store the complexity for the branch on type_defn
.
Later we will see if this is the max complexity among branches.
