Method Detail

projectAs

public <P> QuerydslDataFetcher.Builder<T,P> projectAs(Class<P> projectionType)

Project results returned from the QuerydslPredicateExecutor into the target projectionType. Projection types can be either interfaces with property getters to expose or regular classes outside the entity type hierarchy for DTO projections.

Parameters:

projectionType - projection type

Returns:

a new QuerydslDataFetcher.Builder instance with all previously configured options and projectionType applied

sortBy

public QuerydslDataFetcher.Builder<T,R> sortBy(org.springframework.data.domain.Sort sort)

Apply a Sort order.

Parameters:

sort - the default sort order

Returns:

a new QuerydslDataFetcher.Builder instance with all previously configured options and Sort applied

customizer

public QuerydslDataFetcher.Builder<T,R> customizer(org.springframework.data.querydsl.binding.QuerydslBinderCustomizer<? extends com.querydsl.core.types.EntityPath<T>> customizer)

Apply a QuerydslBinderCustomizer.

If a Querydsl repository implements QuerydslBinderCustomizer itself, this is automatically detected and applied during auto-registration. For manual registration, you will need to use this method to apply it.

Parameters:

customizer - to customize the binding of the GraphQL request to Querydsl Predicate

Returns:

a new QuerydslDataFetcher.Builder instance with all previously configured options and QuerydslBinderCustomizer applied

single

public DataFetcher<R> single()

Build a DataFetcher to fetch single object instances.

many

public DataFetcher<Iterable<R>> many()

Build a DataFetcher to fetch many object instances.
