Overview
This object delegates most methods to a dictionary of functions, @dictionary. @target is passed to the specified function, along with any arguments and block. This allows a method-based DSL without adding methods to the defined class.
Instance Attribute Summary collapse
-
#target ⇒ Object
readonly
The object which will be defined by definition functions.
Instance Method Summary collapse
-
#initialize(target) ⇒ DefinedObjectProxy
constructor
A new instance of DefinedObjectProxy.
-
#method_missing(name, *args, &block) ⇒ Object
Lookup a function from the dictionary and call it if it’s found.
-
#respond_to_missing?(name, include_private = false) ⇒ Boolean
-
#types ⇒ Object
Provides shorthand access to GraphQL’s built-in types.
-
#use(plugin, **kwargs) ⇒ Object
Allow
plugin
to perform complex initialization on the definition.
