java.lang.Object

graphql.schema.GraphQLDirective

All Implemented Interfaces:

GraphQLNamedSchemaElement, GraphQLSchemaElement

Constructor and Description
GraphQLDirective(java.lang.String name, java.lang.String description, java.util.EnumSet<Introspection.DirectiveLocation> locations, java.util.List<GraphQLArgument> arguments) Deprecated. Use the Builder

Method Summary

Modifier and Type	Method and Description
TraversalControl	accept(TraverserContext<GraphQLSchemaElement> context, GraphQLTypeVisitor visitor)
boolean	equals(java.lang.Object o) No GraphQLSchemaElement implements `equals` because we need object identity to treat a GraphQLSchema as an abstract graph.
GraphQLArgument	getArgument(java.lang.String name)
java.util.List<GraphQLArgument>	getArguments()
java.util.List<GraphQLSchemaElement>	getChildren()
SchemaElementChildrenContainer	getChildrenWithTypeReferences()
DirectiveDefinition	getDefinition() The AST Node this schema element is based on.

int	hashCode() No GraphQLSchemaElement implements `equals/hashCode` because we need object identity to treat a GraphQLSchema as an abstract graph.
static GraphQLDirective.Builder	newDirective()
static GraphQLDirective.Builder	newDirective(GraphQLDirective existing)
java.lang.String	toString()
GraphQLDirective	transform(java.util.function.Consumer<GraphQLDirective.Builder> builderConsumer) This helps you transform the current GraphQLDirective into another one by starting a builder with all the current values and allows you to transform it how you want.

Method Detail

getName

public java.lang.String getName()

Specified by:

getName in interface GraphQLNamedSchemaElement

getArguments

public java.util.List<GraphQLArgument> getArguments()

getArgument

public GraphQLArgument getArgument(java.lang.String name)

validLocations

public java.util.EnumSet<Introspection.DirectiveLocation> validLocations()

getDescription

public java.lang.String getDescription()

Specified by:

getDescription in interface GraphQLNamedSchemaElement

getDefinition

public DirectiveDefinition getDefinition()

Description copied from interface: GraphQLNamedSchemaElement

The AST Node this schema element is based on. Is null if the GraphQLSchema is not based on a SDL document. Some elements also have additional extension Nodes. See for example GraphQLObjectType.getExtensionDefinitions()

Specified by:

getDefinition in interface GraphQLNamedSchemaElement

Returns:

Node which this element is based on. Can be null.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

transform

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

This helps you transform the current GraphQLDirective 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<GraphQLSchemaElement> context,
                               GraphQLTypeVisitor visitor)

Specified by:

accept in interface GraphQLSchemaElement

getChildren

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

Specified by:

getChildren in interface GraphQLSchemaElement

getChildrenWithTypeReferences

public SchemaElementChildrenContainer getChildrenWithTypeReferences()

Specified by:

getChildrenWithTypeReferences in interface GraphQLSchemaElement

withNewChildren

public GraphQLDirective withNewChildren(SchemaElementChildrenContainer newChildren)

Specified by:

withNewChildren in interface GraphQLSchemaElement

equals

public final boolean equals(java.lang.Object o)

No GraphQLSchemaElement implements `equals` because we need object identity to treat a GraphQLSchema as an abstract graph.

Specified by:

equals in interface GraphQLSchemaElement

Overrides:

equals in class java.lang.Object

hashCode

public final int hashCode()

No GraphQLSchemaElement implements `equals/hashCode` because we need object identity to treat a GraphQLSchema as an abstract graph.

Specified by:

hashCode in interface GraphQLSchemaElement

Overrides:

hashCode in class java.lang.Object
