Class ResultSetTableModelFactory


  • public final 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 "org.jfree.report.modules.misc.tablemodel.TableFactoryMode" is set to "simple".

      • 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.

        public CloseableTableModel createTableModel​(java.sql.ResultSet rs,
                                                    boolean labelMapping)
                                             throws java.sql.SQLException

        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.
        labelMapping - defines, whether to use column names or column labels to compute the column index.
        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.
