JdbcReader

public JdbcReader(Statement statement)
           throws SQLException

Default constructor.

Parameters:

statement - JDBC statement ready to be executed

Throws:

SQLException - when the statement cannot be used

Method Details

setResultSet

protected void setResultSet(ResultSet resultSet)

Sets the JDBC result set for this reader.

Parameters:

resultSet - the resultSet to set

getResultSet

public ResultSet getResultSet()

Returns the JDBC result set of this reader.

Returns:

the resultSet

close

public void close()

Closes the reader. If the result set was created within this class then it will be closed, too.

Specified by:

close in interface TableReader

Overrides:

close in class AbstractTableReader

See Also:

• TableReader.close()

open

public void open()

Opens the reader.

Specified by:

open in interface TableReader

Overrides:

open in class AbstractTableReader

See Also:

• TableReader.open()

reset

public void reset()

Resets the result set cursor before the first row.

Specified by:

reset in interface TableReader

Overrides:

reset in class AbstractTableReader

See Also:

• TableReader.reset()

readHeaderRow

protected void readHeaderRow()

Reads the header row.

Overrides:

readHeaderRow in class AbstractTableReader

getColumnCount

public int getColumnCount()

Returns the number of columns the result set returns.

Returns:

number of columns

hasNext

public boolean hasNext()

Returns true if there are more rows to be delivered.

See Also:

• Iterator.hasNext()

next

public Object[] next()

Returns the next row.

See Also:

• Iterator.next()

readNextRow

protected void readNextRow()

Reads the next row from the result set.

remove

public void remove()

Forwards to JDBC result set.

See Also:

• Iterator.remove()

isCloseResultSet

public boolean isCloseResultSet()

Returns true if a call to close() will also close the result set.

Returns:

the closeResultSet

setCloseResultSet

public void setCloseResultSet(boolean closeResultSet)

Sets whether the result set will be closed.

Parameters:

closeResultSet - the closeResultSet to set
