Constructor Detail

RepresentationModelAssemblerSupport

public RepresentationModelAssemblerSupport(Class<?> controllerClass,
                                           Class<D> resourceType)

Creates a new RepresentationModelAssemblerSupport using the given controller class and resource type.

Parameters:

controllerClass - must not be null.

resourceType - must not be null.

Method Detail

toCollectionModel

public CollectionModel<D> toCollectionModel(Iterable<? extends T> entities)

Description copied from interface: RepresentationModelAssembler

Converts an Iterable or Ts into an Iterable of RepresentationModel and wraps them in a CollectionModel instance.

Specified by:

toCollectionModel in interface RepresentationModelAssembler<T,D extends RepresentationModel<D>>

Parameters:

entities - must not be null.

Returns:

CollectionModel containing D.

map

public org.springframework.hateoas.server.mvc.RepresentationModelAssemblerSupport.Builder<T,D> map(Iterable<? extends T> entities)

createModelWithId

protected D createModelWithId(Object id,
                              T entity)

Creates a new resource with a self link to the given id.

Parameters:

entity - must not be null.

id - must not be null.

Returns:

createModelWithId

protected D createModelWithId(Object id,
                              T entity,
                              Object... parameters)

instantiateModel

protected D instantiateModel(T entity)

Instantiates the resource object. Default implementation will assume a no-arg constructor and use reflection but can be overridden to manually set up the object instance initially (e.g. to improve performance if this becomes an issue).

Parameters:

entity -

Returns:
