Examples of org.datanucleus.metadata.FieldMetaData

org.datanucleus.metadata.FieldMetaData
Representation of the Meta-Data for a field of a class.
Lifecycle state
An object of this type has 2 lifecycle states. The first is the raw constructed object which represents pure MetaData (maybe from a MetaData file). The second is a "populated" object which represents MetaData for a Field of a class with the metadata aligned to be appropriate for that Field.
Containers
Each field can represent a container. The container can be an array, a Collection or a Map. The field type must be of the correct type to represent these.
Field Management
Each field can be managed by us or not. The class provides a method for identifying if a field is managed by us (isJdoField()). If a field is managed by us, it will have a field "id" (within its class). In a class the field "id" will start at 0 (for the first field, in alphabetical order).
