JDBC API used by UDS

In order to get data from user defined data source, JReport need to invoke the following JDBC API (for details about the API, refer to http://java.sun.com/javase/6/docs/api/).

java.sql.ResultSet

boolean next() throws SQLException
void close() throws SQLException
boolean wasNull() throws SQLException
String getString(int columnIndex) throws SQLException
boolean getBoolean(int columnIndex) throws SQLException
byte getByte(int columnIndex) throws SQLException
short getShort(int columnIndex) throws SQLException
int getInt(int columnIndex) throws SQLException
long getLong(int columnIndex) throws SQLException
float getFloat(int columnIndex) throws SQLException
double getDouble(int columnIndex) throws SQLException
byte[] getBytes(int columnIndex) throws SQLException
java.sql.Date getDate(int columnIndex) throws SQLException
java.sql.Time getTime(int columnIndex) throws SQLException
java.sql.Timestamp getTimestamp(int columnIndex) throws SQLException
java.io.InputStream getAsciiStream(int columnIndex) throws SQLException
java.io.InputStream getBinaryStream(int columnIndex) throws SQLException
ResultSetMetaData getMetaData() throws SQLException
Object getObject(int columnIndex) throws SQLException
int findColumn(String columnLabel) throws SQLException
BigDecimal getBigDecimal(int columnIndex) throws SQLException
Blob getBlob(int columnIndex) throws SQLException
Clob getClob(int columnIndex) throws SQLException

java.sql.ResultSetMetaData

int getColumnCount() throws SQLException
boolean isCurrency(int column) throws SQLException
int isNullable(int column) throws SQLException
int getColumnDisplaySize(int column) throws SQLException
String getColumnLabel(int column) throws SQLException
String getColumnName(int column) throws SQLException
String getSchemaName(int column) throws SQLException
int getPrecision(int column) throws SQLException
int getScale(int column) throws SQLException
String getTableName(int column) throws SQLException
int getColumnType(int column) throws SQLException

Note: The method ResultSetMetaData getMetaData() throws SQLException is only invoked when the Specify columns option is not checked in the Add User Defined Data Source dialog.
