Method Detail

fillImpl

public HyperSpaceSearchCriteria.RandomDiscreteValueSearchCriteria fillImpl(HyperSpaceSearchCriteria.RandomDiscreteValueSearchCriteria impl)

Description copied from class: Schema

Fill an impl object and any children from this schema and its children. If a schema doesn't need to adapt any fields if does not need to override this method.

Overrides:

fillImpl in class Schema<HyperSpaceSearchCriteria.RandomDiscreteValueSearchCriteria,HyperSpaceSearchCriteriaV99.RandomDiscreteValueSearchCriteriaV99>

fillFromImpl

public HyperSpaceSearchCriteriaV99.RandomDiscreteValueSearchCriteriaV99 fillFromImpl(HyperSpaceSearchCriteria.RandomDiscreteValueSearchCriteria impl)

Description copied from class: Schema

Fill this Schema from the given implementation object. If a schema doesn't need to adapt any fields if does not need to override this method.

Overrides:

fillFromImpl in class Schema<HyperSpaceSearchCriteria.RandomDiscreteValueSearchCriteria,HyperSpaceSearchCriteriaV99.RandomDiscreteValueSearchCriteriaV99>
