Method Detail

toGraphQLInputType

public graphql.schema.GraphQLInputType toGraphQLInputType(AnnotatedType javaType,
                                                          Set<Class<? extends TypeMapper>> mappersToSkip,
                                                          TypeMappingEnvironment env)

Specified by:

toGraphQLInputType in interface TypeMapper

Overrides:

toGraphQLInputType in class AbstractTypeSubstitutingMapper<T>

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 TypeSubstituter

Overrides:

getSubstituteType in class AbstractTypeSubstitutingMapper<T>

Parameters:

original - The type to be replaced

Returns:

The substitute type to use for mapping

convertOutput

public graphql.execution.DataFetcherResult<?> convertOutput(graphql.execution.DataFetcherResult<T> original,
                                                            AnnotatedType type,
                                                            ResolutionEnvironment env)

Specified by:

convertOutput in interface OutputConverter<graphql.execution.DataFetcherResult<T>,graphql.execution.DataFetcherResult<?>>

supports

public boolean supports(AnnotatedElement element,
                        AnnotatedType type)

Specified by:

supports in interface OutputConverter<graphql.execution.DataFetcherResult<T>,graphql.execution.DataFetcherResult<?>>

Specified by:

supports in interface TypeMapper

getDerivedTypes

public List<AnnotatedType> getDerivedTypes(AnnotatedType type)

Specified by:

getDerivedTypes in interface DelegatingOutputConverter<graphql.execution.DataFetcherResult<T>,graphql.execution.DataFetcherResult<?>>

isTransparent

public boolean isTransparent()

Description copied from interface: DelegatingOutputConverter

A DelegatingOutputConverter is considered transparent if its sole purpose is to delegate to other converters, and contains no other logic of its own. In other words, if there is no reason to invoke it without other applicable converters present. This flag is purely a performance optimization hint, and is always safe to leave on false.

Specified by:

isTransparent in interface DelegatingOutputConverter<graphql.execution.DataFetcherResult<T>,graphql.execution.DataFetcherResult<?>>

Returns:

A boolean signifying whether the converter is transparent.

getInterceptors

public List<ResolverInterceptor> getInterceptors(ResolverInterceptorFactoryParams params)

Description copied from interface: ResolverInterceptorFactory

Produces inner ResolverInterceptors, invoked around the resolver method.

Calling ResolverInterceptor.Continuation.proceed(InvocationContext) produces the raw (unconverted) result.

Specified by:

getInterceptors in interface ResolverInterceptorFactory

Parameters:

params - Factory parameters

Returns:

a list of outer interceptors

getOuterInterceptors

public List<ResolverInterceptor> getOuterInterceptors(ResolverInterceptorFactoryParams params)

Description copied from interface: ResolverInterceptorFactory

Produces outer ResolverInterceptors, invoked around result conversion.

Calling ResolverInterceptor.Continuation.proceed(InvocationContext) produces the converted result.

Specified by:

getOuterInterceptors in interface ResolverInterceptorFactory

Parameters:

params - Factory parameters

Returns:

a list of outer interceptors
