Class GraphQLInterfaceType

java.lang.Object

graphql.schema.GraphQLInterfaceType

All Implemented Interfaces:

GraphQLCompositeType, GraphQLDirectiveContainer, GraphQLFieldsContainer, GraphQLNullableType, GraphQLOutputType, GraphQLType, GraphQLUnmodifiedType

@PublicApi
public class GraphQLInterfaceType
extends java.lang.Object
implements GraphQLType, GraphQLOutputType, GraphQLFieldsContainer, GraphQLCompositeType, GraphQLUnmodifiedType, GraphQLNullableType, GraphQLDirectiveContainer

In graphql, an interface is an abstract type that defines the set of fields that a type must include to implement that interface. At runtime a TypeResolver is used to take an interface object value and decide what GraphQLObjectType represents this interface type. See http://graphql.org/learn/schema/#interfaces for more details on the concept.

Method Detail

getFieldDefinition

public GraphQLFieldDefinition getFieldDefinition(java.lang.String name)

Specified by:

getFieldDefinition in interface GraphQLFieldsContainer

getFieldDefinitions

public java.util.List<GraphQLFieldDefinition> getFieldDefinitions()

Specified by:

getFieldDefinitions in interface GraphQLFieldsContainer

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()

getTypeResolver

public TypeResolver getTypeResolver()

getDefinition

public InterfaceTypeDefinition 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

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

transform

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

This helps you transform the current GraphQLInterfaceType 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 object 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

newInterface

public static GraphQLInterfaceType.Builder newInterface()

newInterface

public static GraphQLInterfaceType.Builder newInterface(GraphQLInterfaceType existing)
