@Nonnull
default <V> Stream<V> allValuesOf(SingleFeatureBean feature)

Description copied from interface: ManyValueMapper

Retrieves all values of the specified feature.

Specified by:

allValuesOf in interface ManyValueMapper

Parameters:

feature - the bean identifying the multi-valued attribute

Returns:

an immutable ordered Stream over all values

valueFor

@Nonnull
