Types

type Argument

type Argument interface {
	TypeName() string
	// Validate checks if the value that pass in by client is legal.
	Validate(interface{}) error
	GetArgumentType() graphql.Input
}

Argument represents an abstracted definition of GraphQL's conditional querying capabilities. It is decoupled from specific Query implementations, offering a universal and flexible solution for conditional queries. This approach transforms Argument into a reusable component, standardizing condition filtering and data processing across various querying contexts, thereby enhancing the framework's versatility and adaptability.
