Method Details

projecting

public static <M,
D>
EntityProjection.PropertyProjection<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.PropertyProjection.

nonProjecting

public static <M,
D>
EntityProjection.PropertyProjection<M,D> nonProjecting(PropertyPath propertyPath,
 TypeInformation<M> mappedType,
 TypeInformation<D> domainType)

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:

getPropertyPath

public PropertyPath getPropertyPath()

Returns:

the property path representing this property within the root domain type.

toString
