Method Details

multi

public FieldProjectionOptionsStep<?,List<T>> multi()

Description copied from interface: FieldProjectionValueStep

Defines the projection as multi-valued, i.e. returning List<T> instead of T.

Calling FieldProjectionValueStep.multi() is mandatory for multi-valued fields, otherwise the projection will throw an exception upon creating the query.

Specified by:

multi in interface FieldProjectionValueStep<FieldProjectionOptionsStepImpl<T,T>,T>

Returns:

A new step to define optional parameters for the multi-valued projections.

toProjection

public SearchProjection<T> toProjection()

Description copied from interface: ProjectionFinalStep

Create a SearchProjection instance matching the definition given in the previous DSL steps.

Specified by:

toProjection in interface ProjectionFinalStep<T>

Overrides:

toProjection in class FieldProjectionOptionsStepImpl<T,T>

Returns:

The SearchProjection instance.
