Class GraphQLEnumType

java.lang.Object

graphql.schema.GraphQLEnumType

All Implemented Interfaces:

GraphQLDirectiveContainer, GraphQLInputType, GraphQLNullableType, GraphQLOutputType, GraphQLType, GraphQLUnmodifiedType

@PublicApi
public class GraphQLEnumType
extends java.lang.Object
implements GraphQLType, GraphQLInputType, GraphQLOutputType, GraphQLUnmodifiedType, GraphQLNullableType, GraphQLDirectiveContainer

A graphql enumeration type has a limited set of values. This allows you to validate that any arguments of this type are one of the allowed values and communicate through the type system that a field will always be one of a finite set of values. See http://graphql.org/learn/schema/#enumeration-types for more details

                       EnumTypeDefinition definition)

Method Detail

getValues

public java.util.List<GraphQLEnumValueDefinition> getValues()

getValue

public GraphQLEnumValueDefinition getValue(java.lang.String name)

getName

public java.lang.String getName()

Specified by:

getName in interface GraphQLType

Returns:

the name of the type which MUST fit within the regular expression [_A-Za-z][_0-9A-Za-z]*

getDescription

public java.lang.String getDescription()

getCoercing

public Coercing getCoercing()

getDefinition

public EnumTypeDefinition getDefinition()

getDirectives

public java.util.List<GraphQLDirective> getDirectives()

Specified by:

getDirectives in interface GraphQLDirectiveContainer

Returns:

a list of directives associated with the type or field

transform

public GraphQLEnumType transform(java.util.function.Consumer<GraphQLEnumType.Builder> builderConsumer)

This helps you transform the current GraphQLEnumType into another one by starting a builder with all the current values and allows you to transform it how you want.

Parameters:

builderConsumer - the consumer code that will be given a builder to transform

Returns:

a new field based on calling build on that builder

accept

public TraversalControl accept(TraverserContext<GraphQLType> context,
                               GraphQLTypeVisitor visitor)

Description copied from interface: GraphQLType

Double-dispatch entry point. It allows to travers a given non-trivial graphQL type and move from root to nested or enclosed types. This implements similar pattern as Node, see accept(...) for more details about the pattern.

Specified by:

accept in interface GraphQLType

Parameters:

context - TraverserContext bound to this graphQL type object

visitor - Visitor instance that performs actual processing on the types(s)

Returns:

Result of Visitor's operation. Note! Visitor's operation might return special results to control traversal process.

getChildren

public java.util.List<GraphQLType> getChildren()

Specified by:

getChildren in interface GraphQLType

Returns:

returns all types directly associated with this node

newEnum

public static GraphQLEnumType.Builder newEnum()

newEnum

public static GraphQLEnumType.Builder newEnum(GraphQLEnumType existing)
