Interface TypedRow

All Superinterfaces:
Row
public interface TypedRow extends Row

A row that reports the storage class SQLite holds a value in.

SQLite types values, not columns: one column can hold an integer in one row and text in the next, and the typed getters of Row convert whatever is stored. A caller that has to hand the value back as it was stored -- a scripting layer, a generic exporter -- asks for its type first. Reach this through Database#getColumnType(Row, int), which answers Database#COLUMN_UNKNOWN on a row that does not implement it.
