Method Details

schemaDirectiveWiringIsRequired

public static <T extends GraphQLDirectiveContainer>
boolean schemaDirectiveWiringIsRequired(T directiveContainer,
 TypeDefinitionRegistry typeRegistry,
 RuntimeWiring runtimeWiring)

This will return true if something in the RuntimeWiring requires a SchemaDirectiveWiring. This is to allow a shortcut to decide that we don't need ANY SchemaDirectiveWiring post processing

Type Parameters:

T - for two

Parameters:

directiveContainer - the element that has directives

typeRegistry - the type registry

runtimeWiring - the runtime wiring

Returns:

true if something in the RuntimeWiring requires a SchemaDirectiveWiring
