Method Detail

createImpl

public SchemaMetadata createImpl()

Description copied from class: Schema

Create an appropriate implementation object and any child objects but does not fill them. The standard 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<SchemaMetadata,SchemaMetadataV3>

fillImpl

public SchemaMetadata fillImpl(SchemaMetadata 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<SchemaMetadata,SchemaMetadataV3>

fillFromImpl

public SchemaMetadataV3 fillFromImpl(SchemaMetadata 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<SchemaMetadata,SchemaMetadataV3>
