Interface Summary

Interface	Description
Coercing<I,O>	The Coercing interface is used by GraphQLScalarTypes to parse and serialise object values.
DataFetcher<T>	A data fetcher is responsible for returning a data value back for a given graphql field.
DataFetcherFactory<T>	A DataFetcherFactory allows a level of indirection in providing DataFetchers for graphql fields.
DataFetchingEnvironment	A DataFetchingEnvironment instance of passed to a DataFetcher as a execution context and its the place where you can find out information to help you resolve a data value given a graphql field input
DataFetchingFieldSelectionSet	This allows you to retrieve the selection set of fields that have been asked for when the DataFetcher was invoked.
GraphQLCompositeType
GraphQLDirectiveContainer	Represents a graphql object that can have GraphQLDirectives
GraphQLFieldsContainer	Types that can contain output fields are marked with this interface
GraphQLInputFieldsContainer	Types that can contain input fields are marked with this interface
GraphQLInputType	Input types represent those set of types that are allowed to be accepted as graphql mutation input, as opposed to GraphQLOutputTypes which can only be used as graphql response output.
GraphQLModifiedType	A modified type wraps another graphql type and modifies it behavior
GraphQLNullableType
GraphQLOutputType	Output types represent those set of types that are allowed to be sent back as a graphql response, as opposed to GraphQLInputTypes which can only be used as graphql mutation input.
GraphQLType	All types in graphql have a name
GraphQLTypeVisitor
GraphQLUnmodifiedType
SchemaTransformer	These are called by the SchemaGenerator after a valid schema has been built and they can then adjust it accordingly with some sort of post processing.
SelectedField	A SelectedField represents a field that occurred in a query selection set during execution and they are returned from using the DataFetchingFieldSelectionSet interface returned via DataFetchingEnvironment.getSelectionSet()
TypeResolver	This is called during type resolution to work out what concrete GraphQLObjectType should be used dynamically during runtime for GraphQLInterfaceTypes and GraphQLUnionTypes

Class Summary

Class	Description
AsyncDataFetcher<T>	A modifier type that indicates the underlying data fetcher is run asynchronously
DataFetcherFactories	A helper for DataFetcherFactory
DataFetcherFactoryEnvironment	This is passed to a DataFetcherFactory when it is invoked to get a DataFetcher
DataFetchingEnvironmentImpl
DataFetchingEnvironmentImpl.Builder
DataFetchingFieldSelectionSetImpl
FieldCoordinates	A field in graphql is uniquely located within a parent type and hence code elements like DataFetcher need to be specified using those coordinates.
GraphQLArgument	This defines an argument that can be supplied to a graphql field (via GraphQLFieldDefinition.
GraphQLArgument.Builder
GraphQLCodeRegistry	The GraphQLCodeRegistry holds that execution code that is associated with graphql types, namely the DataFetchers associated with fields, the TypeResolvers associated with abstract types and the GraphqlFieldVisibility For legacy reasons these code functions can still exist on the original type objects but this will be removed in a future version.
GraphQLCodeRegistry.Builder
GraphQLDirective	A directive can be used to modify the behavior of a graphql field or type.
GraphQLDirective.Builder
GraphqlElementParentTree	This represents a hierarchy an graphql runtime element upwards to its associated parent elements.
GraphQLEnumType	A graphql enumeration type has a limited set of values.
GraphQLEnumType.Builder
GraphQLEnumValueDefinition	A graphql enumeration type has a limited set of values and this defines one of those unique values See http://graphql.org/learn/schema/#enumeration-types for more details
GraphQLEnumValueDefinition.Builder
GraphQLFieldDefinition	Fields are the ways you get data values in graphql and a field definition represents a field, its type, the arguments it takes and the DataFetcher used to get data values for that field.
GraphQLFieldDefinition.Builder
GraphQLInputObjectField	Input objects defined via GraphQLInputObjectType contains these input fields.
GraphQLInputObjectField.Builder
GraphQLInputObjectType	graphql clearly delineates between the types of objects that represent the output of a query and input objects that can be fed into a graphql mutation.
GraphQLInputObjectType.Builder
GraphQLInterfaceType	In graphql, an interface is an abstract type that defines the set of fields that a type must include to implement that interface.
GraphQLInterfaceType.Builder
GraphQLList	A modified type that indicates there is a list of the underlying wrapped type, eg a list of strings or a list of booleans.
GraphQLNonNull	A modified type that indicates there the underlying wrapped type will not be null.
GraphQLObjectType	This is the work horse type and represents an object with one or more field values that can be retrieved by the graphql system.
GraphQLObjectType.Builder
GraphQLScalarType	A scalar type is a leaf node in the graphql tree of types.
GraphQLScalarType.Builder
GraphQLSchema	The schema represents the combined type system of the graphql engine.
GraphQLSchema.Builder
GraphQLTypeCollectingVisitor
GraphqlTypeComparators
GraphQLTypeReference	A special type to allow a object/interface types to reference itself.
GraphQLTypeResolvingVisitor
GraphQLTypeUtil	A utility class that helps work with GraphQLTypes
GraphQLTypeVisitorStub	Base implementation of GraphQLTypeVisitor for convenience.
GraphQLUnionType	A union type is a polymorphic type that dynamically represents one of more concrete object types.
GraphQLUnionType.Builder
PropertyDataFetcher<T>	This is the default data fetcher used in graphql-java.
SchemaUtil
StaticDataFetcher	A DataFetcher that always returns the same value
TypeResolverProxy
TypeTraverser
