Method Detail

getElement

public T getElement()

Specified by:

getElement in interface SchemaDirectiveWiringEnvironment<T extends GraphQLDirectiveContainer>

Returns:

the runtime element in play

getDirective

public GraphQLDirective getDirective()

Description copied from interface: SchemaDirectiveWiringEnvironment

This returns the directive that the SchemaDirectiveWiring was registered against during calls to RuntimeWiring.Builder.directive(String, SchemaDirectiveWiring)

If this method of registration is not used (say because WiringFactory.providesSchemaDirectiveWiring(SchemaDirectiveWiringEnvironment) or RuntimeWiring.Builder.directiveWiring(SchemaDirectiveWiring) was used) then this will return null.

Specified by:

getDirective in interface SchemaDirectiveWiringEnvironment<T extends GraphQLDirectiveContainer>

Returns:

the directive that was registered under specific directive name or null if it was not registered this way

getAppliedDirective

public GraphQLAppliedDirective getAppliedDirective()

Description copied from interface: SchemaDirectiveWiringEnvironment

This returns the applied directive that the SchemaDirectiveWiring was registered against during calls to RuntimeWiring.Builder.directive(String, SchemaDirectiveWiring)

If this method of registration is not used (say because WiringFactory.providesSchemaDirectiveWiring(SchemaDirectiveWiringEnvironment) or RuntimeWiring.Builder.directiveWiring(SchemaDirectiveWiring) was used) then this will return null.

Specified by:

getAppliedDirective in interface SchemaDirectiveWiringEnvironment<T extends GraphQLDirectiveContainer>

Returns:

the applied directive that was registered under specific directive name or null if it was not registered this way

getDirectives

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

Specified by:

getDirectives in interface SchemaDirectiveWiringEnvironment<T extends GraphQLDirectiveContainer>

Returns:

all of the directives that are on the runtime element

getDirective

public GraphQLDirective getDirective(java.lang.String directiveName)

Description copied from interface: SchemaDirectiveWiringEnvironment

Returns a named directive or null

Specified by:

getDirective in interface SchemaDirectiveWiringEnvironment<T extends GraphQLDirectiveContainer>

Parameters:

directiveName - the name of the directive

Returns:

a named directive or null

getAppliedDirectives

public java.util.Map<java.lang.String,GraphQLAppliedDirective> getAppliedDirectives()

Specified by:

getAppliedDirectives in interface SchemaDirectiveWiringEnvironment<T extends GraphQLDirectiveContainer>

Returns:

all of the directives that are on the runtime element

getAppliedDirective

public GraphQLAppliedDirective getAppliedDirective(java.lang.String directiveName)

Description copied from interface: SchemaDirectiveWiringEnvironment

Returns a named applied directive or null

Specified by:

getAppliedDirective in interface SchemaDirectiveWiringEnvironment<T extends GraphQLDirectiveContainer>

Parameters:

directiveName - the name of the directive

Returns:

a named directive or null

containsDirective

public boolean containsDirective(java.lang.String directiveName)

Description copied from interface: SchemaDirectiveWiringEnvironment

Returns true if the named directive is present

Specified by:

containsDirective in interface SchemaDirectiveWiringEnvironment<T extends GraphQLDirectiveContainer>

Parameters:

directiveName - the name of the directive

Returns:

true if the named directive is present

getNodeParentTree

public NodeParentTree<NamedNode<?>> getNodeParentTree()

Description copied from interface: SchemaDirectiveWiringEnvironment

The node hierarchy depends on the element in question. For example ObjectTypeDefinition nodes have no parent, however a Argument might be on a FieldDefinition which in turn might be on a ObjectTypeDefinition say

Specified by:

getNodeParentTree in interface SchemaDirectiveWiringEnvironment<T extends GraphQLDirectiveContainer>

Returns:

hierarchical graphql language node information

getRegistry

public TypeDefinitionRegistry getRegistry()

Specified by:

getRegistry in interface SchemaDirectiveWiringEnvironment<T extends GraphQLDirectiveContainer>

Returns:

the type registry

getBuildContext

public java.util.Map<java.lang.String,java.lang.Object> getBuildContext()

Specified by:

getBuildContext in interface SchemaDirectiveWiringEnvironment<T extends GraphQLDirectiveContainer>

Returns:

a mpa that can be used by implementors to hold context during the SDL build process

getCodeRegistry

public GraphQLCodeRegistry.Builder getCodeRegistry()

Specified by:

getCodeRegistry in interface SchemaDirectiveWiringEnvironment<T extends GraphQLDirectiveContainer>

Returns:

a builder of the current code registry builder

getFieldsContainer

public GraphQLFieldsContainer getFieldsContainer()

Specified by:

getFieldsContainer in interface SchemaDirectiveWiringEnvironment<T extends GraphQLDirectiveContainer>

Returns:

a GraphQLFieldsContainer when the element is contained with a fields container

getElementParentTree

public GraphqlElementParentTree getElementParentTree()

Description copied from interface: SchemaDirectiveWiringEnvironment

The type hierarchy depends on the element in question. For example GraphQLObjectType elements have no parent, however a GraphQLArgument might be on a GraphQLFieldDefinition which in turn might be on a GraphQLObjectType say

Specified by:

getElementParentTree in interface SchemaDirectiveWiringEnvironment<T extends GraphQLDirectiveContainer>

Returns:

hierarchical graphql type information

getFieldDefinition

public GraphQLFieldDefinition getFieldDefinition()

Specified by:

getFieldDefinition in interface SchemaDirectiveWiringEnvironment<T extends GraphQLDirectiveContainer>

Returns:

a GraphQLFieldDefinition when the element is as field or is contained within one

getFieldDataFetcher

public DataFetcher<?> getFieldDataFetcher()

Description copied from interface: SchemaDirectiveWiringEnvironment

This is useful as a shortcut to get the current fields existing data fetcher

Specified by:

getFieldDataFetcher in interface SchemaDirectiveWiringEnvironment<T extends GraphQLDirectiveContainer>

Returns:

a DataFetcher when the element is as field or is contained within one

setFieldDataFetcher

public GraphQLFieldDefinition setFieldDataFetcher(DataFetcher<?> newDataFetcher)

Description copied from interface: SchemaDirectiveWiringEnvironment

This is a shortcut method to set a new data fetcher in the underlying GraphQLCodeRegistry against the current field.

Often schema directive wiring modify behaviour by wrapping or replacing data fetchers on fields. This method is a helper to make this easier in code.

Specified by:

setFieldDataFetcher in interface SchemaDirectiveWiringEnvironment<T extends GraphQLDirectiveContainer>

Parameters:

newDataFetcher - the new data fetcher to use for this field

Returns:

the environments SchemaDirectiveWiringEnvironment.getFieldDefinition() to allow for a more fluent code style
