public interface ExtendedType

Defines methods to read Java objects from JDBC ResultSets and write as parameters of PreparedStatements.

Method Summary

Methods

Modifier and Type	Method and Description
String	getClassName() Returns a full name of Java class that this ExtendedType supports.
Object	materializeObject(CallableStatement rs, int index, int type) Reads an object from a stored procedure OUT parameter, converting it to class returned by 'getClassName' method.
Object	materializeObject(ResultSet rs, int index, int type) Reads an object from JDBC ResultSet column, converting it to class returned by 'getClassName' method.
void	setJdbcObject(PreparedStatement statement, Object value, int pos, int type, int scale) Initializes a single parameter of a PreparedStatement with object value.

Method Detail

getClassName

String getClassName()

Returns a full name of Java class that this ExtendedType supports.

setJdbcObject

void setJdbcObject(PreparedStatement statement,
                 Object value,
                 int pos,
                 int type,
                 int scale)
                   throws Exception

Throws:

Exception

materializeObject

Object materializeObject(ResultSet rs,
                       int index,
                       int type)
                         throws Exception

Reads an object from JDBC ResultSet column, converting it to class returned by 'getClassName' method.

Throws:

Exception - if read error occurred, or an object can't be converted to a target Java class.

materializeObject
