org.datanucleus.metadata.MetaData
Base class for all MetaData.
MetaData Lifecycle
The states represent the lifecycle of a MetaData object. The lifecycle goes as follows :
1. MetaData object is created (values passed in from a parsed file, or manually generated)
2. MetaData object is populated (maybe pass in a class that it represents, creating any additional information that wasn't in the initial data).
3. MetaData object is initialised (any internal arrays are set up, and additions of data is blocked from this point).
4. MetaData object is added to with runtime information like actual column names and types in use.
MetaData Extensability

All MetaData elements are extensible with extensions for a "vendor-name". Extensions take the form of a key and a value.
