Class MapToListTypeAdapter<K,V>

java.lang.Object

io.leangen.graphql.generator.mapping.common.AbstractTypeSubstitutingMapper<S>

io.leangen.graphql.generator.mapping.AbstractTypeAdapter<Map<K,V>,List<MapToListTypeAdapter.MapEntry<K,V>>>

io.leangen.graphql.generator.mapping.common.MapToListTypeAdapter<K,V>

All Implemented Interfaces:

InputConverter<Map<K,V>,List<MapToListTypeAdapter.MapEntry<K,V>>>, OutputConverter<Map<K,V>,List<MapToListTypeAdapter.MapEntry<K,V>>>, TypeMapper

public class MapToListTypeAdapter<K,V>
extends AbstractTypeAdapter<Map<K,V>,List<MapToListTypeAdapter.MapEntry<K,V>>>

As maps are dynamic structures with no equivalent in GraphQL, they require special treatment. This adapter turns a map into a list of key-value pairs (instances of MapToListTypeAdapter.MapEntry).
