Parameters:

name - the field name of the entity

Returns:

the restricted view

from

RefineableView<E> from(String name,
                       Comparable value)

Parameters:

name - the field name of the entity

Returns:

the restricted view

fromAfter

RefineableView<E> fromAfter(String name,
                            Comparable value)

Parameters:

name - the field name of the entity

Returns:

the restricted view

to

RefineableView<E> to(String name,
                     Comparable value)

Creates a sub-View, restricted to entities whose name field is less than or equal to the given value.

Parameters:

name - the field name of the entity

Returns:

the restricted view

toBefore

RefineableView<E> toBefore(String name,
                           Comparable value)
