Method Summary

Modifier and Type	Method	Description
void	clear()	The expected behavior of the implementation is to put the informations into an uninitialized state.
void	displayStudent()	The general contract of displayStudent is feeding the model with averages for each course for each period for a student.
Class<?>	getColumnClass(int columnIndex)
int	getQuotationMaximum(int row)	Returns the Examination maximum value (ie.
Student	getStudent()
boolean	hasDelatedQuotations()	If we delete a Quotation from the table, it is not deleted from the persistent layer until the save operation is not performed. The hasDelatedQuotations methods may be called if we want to set the enable state of a save button, or to inform the client than it remains not deleted quotations.
boolean	isCellEditable(int row, int column)
void	propertyChange(PropertyChangeEvent evt)
void	saveAll()	The general contract of saveAll is that each row is saved or updated into persistent layer.
void	setStudent(Student _student)	The general contract of setStudent is storing the student into the model and calling the displayStudent() method after.

Constructor Details

PeriodAVGTableModel

public PeriodAVGTableModel()

Method Details

getStudent

public Student getStudent()

Specified by:

getStudent in interface IAVGTableModel

Returns:

the student

setStudent

public void setStudent(Student _student)

Description copied from interface: IAVGTableModel

The general contract of setStudent is storing the student into the model and calling the displayStudent() method after.

Specified by:

setStudent in interface IAVGTableModel

Parameters:

_student - the student to set

displayStudent

public void displayStudent()

Description copied from interface: IAVGTableModel

The general contract of displayStudent is feeding the model with averages for each course for each period for a student.

Specified by:

displayStudent in interface IAVGTableModel

propertyChange

public void propertyChange(PropertyChangeEvent evt)

Specified by:

propertyChange in interface PropertyChangeListener

getQuotationMaximum

public int getQuotationMaximum(int row)

Description copied from interface: IQuotationsTableModel

Returns the Examination maximum value (ie. to compute the average)

Specified by:

getQuotationMaximum in interface IQuotationsTableModel

Parameters:

row - index of the row containing the Quotation. This is required for quotations tables, but in some cases the implementation of this does not use the row (in the examination table, the maximum value is not stored into a row)

Returns:

the maximum possible value for a quotation (stored into examination)

saveAll

public void saveAll()

Description copied from interface: IQuotationsTableModel

The general contract of saveAll is that each row is saved or updated into persistent layer. If the IQuotationsTableModel.hasDelatedQuotations() method returns true, all deleted Quotation must be deleted into persistent layer.
The list of deletedQuotations will be empty after this.

Specified by:

saveAll in interface IQuotationsTableModel

hasDelatedQuotations

public boolean hasDelatedQuotations()

Description copied from interface: IQuotationsTableModel

If we delete a Quotation from the table, it is not deleted from the persistent layer until the save operation is not performed.
The hasDelatedQuotations methods may be called if we want to set the enable state of a save button, or to inform the client than it remains not deleted quotations.

Specified by:

hasDelatedQuotations in interface IQuotationsTableModel

Returns:

true if there remains quotations to delete

clear

public void clear()

Description copied from interface: IClearable

The expected behavior of the implementation is to put the informations into an uninitialized state. See the implementation to know the fields affected by this method.

Specified by:

clear in interface IClearable

getColumnClass

public Class<?> getColumnClass(int columnIndex)

Specified by:

getColumnClass in interface TableModel

Overrides:

getColumnClass in class AbstractTableModel

isCellEditable

public boolean isCellEditable(int row,
 int column)

Specified by:

isCellEditable in interface TableModel

Overrides:

isCellEditable in class DefaultTableModel
