Method Detail

createImpl

public I createImpl()

Description copied from class: Schema

Create an implementation object and any child objects but DO NOT fill them. The purpose of a createImpl without a fillImpl is to be able to get the default values for all the impl's fields.

For objects without children this method does all the required work. For objects with children the subclass will need to override, e.g. by calling super.createImpl() and then calling createImpl() on its children.

Note that impl objects for schemas which override this method don't need to have a default constructor (e.g., a Keyed object constructor can still create and set the Key), but they must not fill any fields which can be filled later from the schema.

TODO: We *could* handle the common case of children with the same field names here by finding all of our fields that are themselves Schemas.

Overrides:

createImpl in class Schema<I extends ConfusionMatrix,ConfusionMatrixBase<I extends ConfusionMatrix,S extends ConfusionMatrixBase>>

fillFromImpl

public S fillFromImpl(I cm)

Description copied from class: Schema

Version and Schema-specific filling from the implementation object.

Overrides:

fillFromImpl in class Schema<I extends ConfusionMatrix,ConfusionMatrixBase<I extends ConfusionMatrix,S extends ConfusionMatrixBase>>
