/**

* 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.

* <p>

* For more info see <a href="https://graphql.org/learn/schema/#scalar-types">https://graphql.org/learn/schema/#scalar-types</a> and

/**

* This represents the "Int" type as defined in the graphql specification : <a href="https://spec.graphql.org/October2021/#sec-Int">...</a>

* <p>

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

public static final GraphQLScalarType GraphQLInt = GraphQLScalarType.newScalar()

.name("Int").description("Built-in Int").coercing(new GraphqlIntCoercing()).build();

/**

* This represents the "Float" type as defined in the graphql specification : <a href="https://spec.graphql.org/October2021/#sec-Float">...</a>

* <p>

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

public static final GraphQLScalarType GraphQLFloat = GraphQLScalarType.newScalar()

.name("Float").description("Built-in Float").coercing(new GraphqlFloatCoercing()).build();

/**

* This represents the "String" type as defined in the graphql specification : <a href="https://spec.graphql.org/October2021/#sec-String">...</a>

public static final GraphQLScalarType GraphQLString = GraphQLScalarType.newScalar()

.name("String").description("Built-in String").coercing(new GraphqlStringCoercing()).build();

/**

* This represents the "Boolean" type as defined in the graphql specification : <a href="https://spec.graphql.org/October2021/#sec-Boolean">...</a>

public static final GraphQLScalarType GraphQLBoolean = GraphQLScalarType.newScalar()

.name("Boolean").description("Built-in Boolean").coercing(new GraphqlBooleanCoercing()).build();

/**

* This represents the "ID" type as defined in the graphql specification : <a href="https://spec.graphql.org/October2021/#sec-ID">...</a>

* <p>

* 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.

public static final GraphQLScalarType GraphQLID = GraphQLScalarType.newScalar()

.name("ID").description("Built-in ID").coercing(new GraphqlIDCoercing()).build();
