Interface ResultGetter

All Known Implementing Classes:

ResultGetterImpl

public interface ResultGetter

Allows values to be retrieved from the underlying result set. TypeHandlerCallback implementations use this interface to get values that they can subsequently manipulate before having them returned. Each of these methods has a corresponding method on the ResultSet (or CallableStatement) class, the only difference being that there is no need to specify the column name or index with these methods.

注意: There is no need to implement this. The implementation will be passed into the TypeHandlerCallback automatically.
