public interface RootTable

Interface that is implemented by all Root tables. A Root table is a non- virtual table that represents table data in its lowest form. When the Table.resolveToRawTable method is called, if it encounters a table that implements RootTable then it does not attempt to decend further to extract the underlying tables.

This interface is used for unions.
