java.io.Serializable, javax.swing.table.TableModel

public class IsoTableModel

extends javax.swing.table.AbstractTableModel

IsoTableModel creates a 2-column Transaction-Isolation Preview table used in IsolationFrame

 JY10/30/00 corrected errors involving numbering the isolation levels,
 thus eliminating discrepancies between Sybase's numerical definition for
 different isolation levels and TPPT tool's definition as shown in the
 isolation frame

boolean	isCellEditable(int row, int col) Sets the cell at position [row, col] to be non-editable
protected int	isoLevelToNum(java.lang.String level) Converts the isolation level from string representation to numerical form
java.lang.String	isoLevelToString(int level) Converts the isolation level from numerical form to string representation
void	setDefault() Sets every transaction type to be default isolation level
void	setGlobalTransIso() If the user has changed the isolation level of any transaction type, update the information in global transaction table GlobalData.transactions.
boolean	SetTransIsoList() Constructs the content of preview table by extracting information about each transaction type and current isolation level from the global transaction table GlobalData.transactions
void	setValueAt(java.lang.Object value, int row, int col) Sets the cell value for cell position [row, col]
