- * A simple interface for implementing custom type handlers.

- * the framework to handle types that are not supported, or
- * handle supported types in a different way. For example,
- * you might use a custom type handler to implement proprietary
- * BLOB support (e.g. Oracle), or you might use it to handle
- * booleans using "Y" and "N" instead of the more typical 0/1.
