Package io.leangen.graphql.generator.mapping.common

Class MapToListTypeAdapter

java.lang.Object

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

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

io.leangen.graphql.generator.mapping.common.MapToListTypeAdapter

All Implemented Interfaces:

DelegatingOutputConverter<Map<?,?>,List<MapToListTypeAdapter.MapEntry<?,?>>>, InputConverter<Map<?,?>,List<MapToListTypeAdapter.MapEntry<?,?>>>, OutputConverter<Map<?,?>,List<MapToListTypeAdapter.MapEntry<?,?>>>, TypeMapper, TypeSubstituter

public class MapToListTypeAdapter
extends AbstractTypeAdapter<Map<?,?>,List<MapToListTypeAdapter.MapEntry<?,?>>>
implements DelegatingOutputConverter<Map<?,?>,List<MapToListTypeAdapter.MapEntry<?,?>>>

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).

Method Detail

convertOutput

public List<MapToListTypeAdapter.MapEntry<?,?>> convertOutput(Map<?,?> original,
                                                                    AnnotatedType type,
                                                                    ResolutionEnvironment resolutionEnvironment)

Specified by:

convertOutput in interface OutputConverter<Map<?,?>,List<MapToListTypeAdapter.MapEntry<?,?>>>

convertInput

public Map<?,?> convertInput(List<MapToListTypeAdapter.MapEntry<?,?>> original,
                                   AnnotatedType type,
                                   GlobalEnvironment environment,
                                   ValueMapper valueMapper)

Specified by:

convertInput in interface InputConverter<Map<?,?>,List<MapToListTypeAdapter.MapEntry<?,?>>>

getSubstituteType

public AnnotatedType getSubstituteType(AnnotatedType original)

Description copied from class: AbstractTypeSubstitutingMapper

Returns the type to map instead of the original. This implementation always returns the type of the generic type parameter S.

Specified by:

getSubstituteType in interface InputConverter<Map<?,?>,List<MapToListTypeAdapter.MapEntry<?,?>>>

Specified by:

getSubstituteType in interface TypeSubstituter

Overrides:

getSubstituteType in class AbstractTypeSubstitutingMapper<List<MapToListTypeAdapter.MapEntry<?,?>>>

Parameters:

original - The type to be replaced

Returns:

The substitute type to use for mapping

getDerivedTypes

public List<AnnotatedType> getDerivedTypes(AnnotatedType mapType)

Specified by:

getDerivedTypes in interface DelegatingOutputConverter<Map<?,?>,List<MapToListTypeAdapter.MapEntry<?,?>>>

supports

public boolean supports(AnnotatedType type)

Specified by:

supports in interface InputConverter<Map<?,?>,List<MapToListTypeAdapter.MapEntry<?,?>>>

Overrides:

supports in class AbstractTypeAdapter<Map<?,?>,List<MapToListTypeAdapter.MapEntry<?,?>>>
