static boolean	isWrapped(GraphQLType type) Returns true if the given type is a non null or list type, that is a wrapped type
static java.lang.String	simplePrint(GraphQLSchemaElement schemaElement)
static java.lang.String	simplePrint(GraphQLType type) This will return the type in graphql SDL format, eg [typeName!]!
static GraphQLUnmodifiedType	unwrapAll(GraphQLType type) Unwraps all layers of the type or just returns the type again if its not a wrapped type
static GraphQLType	unwrapNonNull(GraphQLType type)
static GraphQLType	unwrapOne(GraphQLType type) Unwraps one layer of the type or just returns the type again if its not a wrapped type
static java.util.Stack<GraphQLType>	unwrapType(GraphQLType type) graphql types can be wrapped in GraphQLNonNull and GraphQLList type wrappers so this method will unwrap the type down to the raw unwrapped type and return that wrapping as a stack, with the top of the stack being the raw underling type.

the underlying type

unwrapNonNull

public static GraphQLType unwrapNonNull(GraphQLType type)

unwrapType

public static java.util.Stack<GraphQLType> unwrapType(GraphQLType type)

graphql types can be wrapped in GraphQLNonNull and GraphQLList type wrappers so this method will unwrap the type down to the raw unwrapped type and return that wrapping as a stack, with the top of the stack being the raw underling type.

Parameters:

type - the type to unwrap

Returns:

a stack of the type wrapping which will be at least 1 later deep
