@PublicApi
public class Scalars
extends Object

This contains the implementations of the Scalar types that ship with graphql-java. Some are proscribed by the graphql specification (Int, Float, String, Boolean and ID) while others are offer because they are common on Java platforms.

For more info see https://graphql.org/learn/schema/#scalar-types and more specifically https://spec.graphql.org/draft/#sec-Scalars

Field Details

GraphQLInt

public static final GraphQLScalarType GraphQLInt

This represents the "Int" type as defined in the graphql specification : https://spec.graphql.org/October2021/#sec-Int

The Int scalar type represents a signed 32‐bit numeric non‐fractional value.

GraphQLFloat

public static final GraphQLScalarType GraphQLFloat

This represents the "Float" type as defined in the graphql specification : https://spec.graphql.org/October2021/#sec-Float

Note: The Float type in GraphQL is equivalent to Double in Java. (double precision IEEE 754)

GraphQLString

public static final GraphQLScalarType GraphQLString

This represents the "String" type as defined in the graphql specification : https://spec.graphql.org/October2021/#sec-String

GraphQLBoolean

public static final GraphQLScalarType GraphQLBoolean

This represents the "Boolean" type as defined in the graphql specification : https://spec.graphql.org/October2021/#sec-Boolean

GraphQLID

public static final GraphQLScalarType GraphQLID

This represents the "ID" type as defined in the graphql specification : https://spec.graphql.org/October2021/#sec-ID

The ID scalar type represents a unique identifier, often used to re-fetch an object or as the key for a cache. The ID type is serialized in the same way as a String; however, it is not intended to be human‐readable. While it is often numeric, it should always serialize as a String.
