Class GraphQLSchema

java.lang.Object

graphql.schema.GraphQLSchema

@PublicApi
public class GraphQLSchema
extends java.lang.Object

The schema represents the combined type system of the graphql engine. This is how the engine knows what graphql queries represent what data.

See http://graphql.org/learn/schema/#type-language for more details

Constructor Detail

GraphQLSchema

@Deprecated
public GraphQLSchema(GraphQLObjectType queryType)

Deprecated. use the newSchema() builder pattern instead, as this constructor will be made private in a future version.

Parameters:

queryType - the query type

GraphQLSchema

@Deprecated
public GraphQLSchema(GraphQLObjectType queryType,
                                 GraphQLObjectType mutationType,
                                 java.util.Set<GraphQLType> additionalTypes)

Deprecated. use the newSchema() builder pattern instead, as this constructor will be made private in a future version.

Parameters:

queryType - the query type

mutationType - the mutation type

additionalTypes - additional types

GraphQLSchema

@Deprecated
public GraphQLSchema(GraphQLObjectType queryType,
                                 GraphQLObjectType mutationType,
                                 GraphQLObjectType subscriptionType,
                                 java.util.Set<GraphQLType> additionalTypes)

Deprecated. use the newSchema() builder pattern instead, as this constructor will be made private in a future version.

Parameters:

queryType - the query type

mutationType - the mutation type

subscriptionType - the subscription type

additionalTypes - additional types

Method Detail

getCodeRegistry

public GraphQLCodeRegistry getCodeRegistry()

getAdditionalTypes

public java.util.Set<GraphQLType> getAdditionalTypes()

getType

public GraphQLType getType(java.lang.String typeName)

getObjectType

public GraphQLObjectType getObjectType(java.lang.String typeName)

Called to return a named GraphQLObjectType from the schema

Parameters:

typeName - the name of the type

Returns:

a graphql object type or null if there is one

Throws:

GraphQLException - if the type is NOT a object type

getTypeMap

public java.util.Map<java.lang.String,GraphQLNamedType> getTypeMap()

getAllTypesAsList

public java.util.List<GraphQLNamedType> getAllTypesAsList()

getImplementations

public java.util.List<GraphQLObjectType> getImplementations(GraphQLInterfaceType type)

This will return the list of GraphQLObjectType types that implement the given interface type.

Parameters:

type - interface type to obtain implementations of.

Returns:

list of types implementing provided interface

isPossibleType

public boolean isPossibleType(GraphQLNamedType abstractType,
                              GraphQLObjectType concreteType)

Returns true if a specified concrete type is a possible type of a provided abstract type. If the provided abstract type is: - an interface, it checks whether the concrete type is one of its implementations. - a union, it checks whether the concrete type is one of its possible types.

Parameters:

abstractType - abstract type either interface or union

concreteType - concrete type

Returns:

true if possible type, false otherwise.

getQueryType

public GraphQLObjectType getQueryType()

getMutationType

public GraphQLObjectType getMutationType()

getSubscriptionType

public GraphQLObjectType getSubscriptionType()

getFieldVisibility

@Deprecated
public GraphqlFieldVisibility getFieldVisibility()

Deprecated. use GraphQLCodeRegistry.getFieldVisibility() instead

Returns:

the field visibility

getDirectives

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

This returns the list of directives that are associated with this schema object including built in ones.

Returns:

a list of directives

getDirectiveByName

public java.util.Map<java.lang.String,GraphQLDirective> getDirectiveByName()

This returns a map of directives that are associated with this schema object including built in ones.

Returns:

a map of directives

getDirective

public GraphQLDirective getDirective(java.lang.String name)

getSchemaDirectives

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

This returns the list of directives that have been explicitly put on the schema object. Note that getDirectives() will return directives for all schema elements, whereas this is just for the schema element itself

Returns:

a list of directives

getSchemaDirectiveByName

public java.util.Map<java.lang.String,GraphQLDirective> getSchemaDirectiveByName()

This returns a map of directives that have been explicitly put on the schema object. Note that getDirectives() will return directives for all schema elements, whereas this is just for the schema element itself

Returns:

a list of directives

getSchemaDirective

public GraphQLDirective getSchemaDirective(java.lang.String name)

This returns the named directive that have been explicitly put on the schema object. Note that getDirective(String) will return directives for all schema elements, whereas this is just for the schema element itself

Returns:

a named directive

getDefinition

public SchemaDefinition getDefinition()

getExtensionDefinitions

public java.util.List<SchemaExtensionDefinition> getExtensionDefinitions()

isSupportingMutations

public boolean isSupportingMutations()

isSupportingSubscriptions

public boolean isSupportingSubscriptions()

transform

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

This helps you transform the current GraphQLSchema object 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 GraphQLSchema object based on calling build on that builder

newSchema

public static GraphQLSchema.Builder newSchema()

Returns:

a new schema builder

newSchema

public static GraphQLSchema.Builder newSchema(GraphQLSchema existingSchema)

This allows you to build a schema from an existing schema. It copies everything from the existing schema and then allows you to replace them.

Parameters:

existingSchema - the existing schema

Returns:

a new schema builder
