Constructor Detail

MetaColumnTableModel

public MetaColumnTableModel(List<MetaColumn> metaList)
Constructs a new MetaColumnTableModel.

Parameters:
metaList - a list of MetaColumn objects
Method Detail

getColumnCount

public int getColumnCount()

getRowCount

public abstract int getRowCount()

getValueAt

public Object getValueAt(int irow,
                         int icol)

setValueAt

public void setValueAt(Object value,
                       int irow,
                       int icol)
Specified by:
setValueAt in interface TableModel
Overrides:
setValueAt in class AbstractTableModel

getColumnClass

public Class getColumnClass(int icol)
Specified by:
getColumnClass in interface TableModel
Overrides:
getColumnClass in class AbstractTableModel

getColumnName

public String getColumnName(int icol)
Specified by:
getColumnName in interface TableModel
Overrides:
getColumnName in class AbstractTableModel

isCellEditable

public boolean isCellEditable(int irow,
                              int icol)
Specified by:
isCellEditable in interface TableModel
Overrides:
isCellEditable in class AbstractTableModel

getColumnList

public List<MetaColumn> getColumnList()
Returns the list of columns which provide the data for this model. The list may be altered (but fire appropriate events if you do it on a live instance).

Returns:
column list

canSort

public boolean canSort(MetaColumn sortCol)
Indicates whether the supplied column has a defined sort order.

Parameters:
sortCol - column, not null
Returns:
true iff sortCol can be sorted on

sortRows

public boolean sortRows(MetaColumn sortCol,
                        boolean isDescending)
Reorders the rows of this table model based on the contents of one of its columns. This method does not inform listeners that the table data may have changed, so calling code should do that where appropriate. It only needs to do so if the return value of this method is true.

Parameters:
sortCol - column to sort on, or null for natural ordering
isDescending - false to sort up, true to sort down
Returns:
true if changes may have been made to the rows, false if no changes were made

getListIndex

public int getListIndex(int irow)
Returns the index in the natural row sequence for a row index in the table model.

Parameters:
irow - table row index
Returns:
list row index
