Method Detail

sensibleGroupedOrder

public static java.util.Comparator<GraphQLSchemaElement> sensibleGroupedOrder()

This orders the schema into a sensible grouped order

Returns:

a comparator that allows for sensible grouped order

unwrapElement

private static GraphQLSchemaElement unwrapElement(GraphQLSchemaElement element)

compareByName

private static int compareByName(GraphQLSchemaElement o1,
                                 GraphQLSchemaElement o2)

getComparator

public <T extends GraphQLSchemaElement> java.util.Comparator<? super T> getComparator(GraphqlTypeComparatorEnvironment environment)

Search for the most to least specific registered Comparator otherwise a default is returned.

Specified by:

getComparator in interface GraphqlTypeComparatorRegistry

Type Parameters:

T - the type of the comparator

Parameters:

environment - Defines the scope to control where the Comparator can be applied.

Returns:

The registered Comparator or null if not found.

defaultComparators

public static GraphqlTypeComparatorRegistry defaultComparators()

Returns:

A registry where all GraphQLTypes receive a default Comparator by comparing GraphQLType::getName.

newComparators
