- All Superinterfaces:
public interface CustomColumnResolvingTable extends Table
Table that specifies a custom way to resolve column
It is optional for a Table to implement this interface. If Table does not implement this interface, column resolving will be performed in the default way.
NOTE: This class is experimental and subject to change/removal without notice.
List<String>>>resolveColumn (RelDataType rowType, RelDataTypeFactory typeFactory, List<String> names)Resolve a column based on the name components. One or more the input name components can be resolved to one field in the table row type, along with a remainder list of name components which have not been resolved within this call, and which in turn can be potentially resolved as sub-field names. In the meantime, this method can return multiple matches, which is a list of pairs containing the resolved field and the remaining name components.
rowType- the table row type
typeFactory- the type factory
names- the name components to be resolved
- a list of pairs containing the resolved field and the remaining name components.
