Package org.springframework.data.projection

Class EntityProjection.ContainerPropertyProjection<M,D>

java.lang.Object

org.springframework.data.projection.EntityProjection<M,D>

org.springframework.data.projection.EntityProjection.PropertyProjection<M,D>

org.springframework.data.projection.EntityProjection.ContainerPropertyProjection<M,D>

Type Parameters:

M - the mapped type acting as view onto the domain type.

D - the domain type.

All Implemented Interfaces:

Iterable<EntityProjection.PropertyProjection<?,?>>, Supplier<Stream<EntityProjection.PropertyProjection<?,?>>>, Streamable<EntityProjection.PropertyProjection<?,?>>

Enclosing class:

EntityProjection<M,D>

public static class EntityProjection.ContainerPropertyProjection<M,D>
extends EntityProjection.PropertyProjection<M,D>

Descriptor for a property-level type along its potential projection that is held within a Collection-like or Map-like container. Property paths within containers use the deeply unwrapped actual type of the container as root type and as they cannot be tied immediately to the root entity.

Method Details

projecting

public static <M,
D>
EntityProjection.ContainerPropertyProjection<M,D> projecting(PropertyPath propertyPath,
 TypeInformation<M> mappedType,
 TypeInformation<D> domainType,
 List<EntityProjection.PropertyProjection<?,?>> properties,
 EntityProjection.ProjectionType projectionType)

Create a projecting variant of a mapped type.

Parameters:

propertyPath - the path to the actual property.

mappedType - the target projection type. Must not be null.

domainType - the source domain type. Must not be null.

properties - properties to include.

projectionType - must not be null.

Returns:

new instance of EntityProjection.ContainerPropertyProjection.

nonProjecting

public static <M,
D>
EntityProjection.ContainerPropertyProjection<M,D> nonProjecting(PropertyPath propertyPath,
 TypeInformation<M> mappedType,

Create a non-projecting variant of a mapped type.

Parameters:

propertyPath - the path to the actual property.

mappedType - the target projection type. Must not be null.

domainType - the source domain type. Must not be null.

Returns:

new instance of EntityProjection.ContainerPropertyProjection.
