Class ResultSetTableModelFactory

java.lang.Object
  com.jrefinery.report.tablemodel.ResultSetTableModelFactory

public class ResultSetTableModelFactory

extends java.lang.Object

Creates a TableModel which is backed up by a ResultSet. If the ResultSet is scrollable, a ScrollableResultSetTableModel is created, otherwise all data is copied from the ResultSet into a DefaultTableModel.

The creation of a DefaultTableModel can be forced if the system property "com.jrefinery.report.TableFactoryMode" is set to "simple".

Method Detail

createTableModel

public CloseableTableModel createTableModel(java.sql.ResultSet rs)
                                     throws java.sql.SQLException

Creates a table model by using the given ResultSet as the backend. If the ResultSet is scrollable (the type is not TYPE_FORWARD_ONLY), an instance of ScrollableResultSetTableModel is returned. This model uses the extended capabilities of scrollable resultsets to directly read data from the database without caching or the need of copying the complete ResultSet into the programs memory.

If the ResultSet lacks the scollable features, the data will be copied into a DefaultTableModel and the ResultSet gets closed.

Parameters:

rs - the result set.

Returns:

a closeable table model.

Throws:

java.sql.SQLException - if there is a problem with the result set.

generateDefaultTableModel

public CloseableTableModel generateDefaultTableModel(java.sql.ResultSet rs)
                                              throws java.sql.SQLException

Generates a TableModel that gets its contents filled from a ResultSet. The column names of the ResultSet will form the column names of the table model.

Hint: To customize the names of the columns, use the SQL column aliasing (done with SELECT nativecolumnname AS "JavaColumnName" FROM ....

Parameters:

rs - the result set.

Returns:

a closeable table model.

Throws:

java.sql.SQLException - if there is a problem with the result set.

getInstance

public static ResultSetTableModelFactory getInstance()

Returns the singleton instance of the factory.

Returns:

an instance of this factory.
