Instance Attribute Summary collapse
-
#argument_definitions ⇒ Array<GraphQL::Node::Argument>
readonly
Arguments which have been entered.
-
#directive_definitions ⇒ Array<GraphQL::Node::Directive>
readonly
Directives are pushed on, then popped off while traversing the tree.
-
#field_definitions ⇒ Array<GraphQL::Field>
readonly
When it enters a field, it’s pushed on this stack (useful for nested fields, args).
-
#object_types ⇒ Array<GraphQL::ObjectType, GraphQL::Union, GraphQL::Interface>
readonly
When it enters an object (starting with query or mutation root), it’s pushed on this stack.
-
#path ⇒ Array<String>
readonly
Fields which have been entered (by their AST name).
-
#schema ⇒ GraphQL::Schema
readonly
The schema whose types are present in this document.
