Class SubSetTableModel
java.lang.Object
org.jfree.report.modules.misc.tablemodel.SubSetTableModel
- TableModel
extends java.lang.Object
implements TableModel
A TableModel that proxies an other tablemodel and cuts rows from the start and/or the
end of the other tablemodel.
SubSetTableModel(int start, int end, TableModel model) - Creates a new SubSetTableModel, the start and the end parameters define the new
tablemodel row count.
|
void | addTableModelListener(TableModelListener l) - Adds a listener to the list that is notified each time a change to the data model
occurs.
|
Class | getColumnClass(int columnIndex) - Returns the most specific superclass for all the cell values in the column.
|
int | getColumnCount() - Returns the number of columns in the model.
|
String | getColumnName(int columnIndex) - Returns the name of the column at
columnIndex .
|
protected TableModel | getEnclosedModel() - Returns the enclosed tablemodel, which is wrapped by this subset table model.
|
protected int | getEnd() - Returns the last row that should be visible.
|
int | getRowCount() - Returns the number of rows in the model.
|
protected int | getStart() - Returns the start row that should be mapped to row 0 of this model.
|
Object | getValueAt(int rowIndex, int columnIndex) - Returns the value for the cell at
columnIndex and
rowIndex .
|
boolean | isCellEditable(int rowIndex, int columnIndex) - Returns true if the cell at
rowIndex and columnIndex is
editable.
|
void | removeTableModelListener(TableModelListener l) - Removes a listener from the list that is notified each time a change to the data
model occurs.
|
void | setValueAt(Object aValue, int rowIndex, int columnIndex) - Sets the value in the cell at
columnIndex and rowIndex to
aValue .

SubSetTableModel
public SubSetTableModel(int start,
int end,
TableModel model)
Creates a new SubSetTableModel, the start and the end parameters define the new
tablemodel row count. The parameter start
must be a positive integer and
denotes the number or rows removed from the start of the tablemodel. end
is the number of the last translated row. Any row after end
is ignored.
End must be greater or equal the given start row.
start
- the number of rows that should be removed.end
- the last row.model
- the wrapped model
addTableModelListener
public void addTableModelListener(TableModelListener l)
Adds a listener to the list that is notified each time a change to the data model
occurs.
l
- the TableModelListener
getColumnClass
public Class getColumnClass(int columnIndex)
Returns the most specific superclass for all the cell values in the column. This is
used by the JTable
to set up a default renderer and editor for the
column.
columnIndex
- the index of the column
- the base ancestor class of the object values in the model.
getColumnCount
public int getColumnCount()
Returns the number of columns in the model. A JTable
uses this method to
determine how many columns it should create and display by default.
- the number of columns in the model
getColumnName
public String getColumnName(int columnIndex)
Returns the name of the column at columnIndex
. This is used to
initialize the table's column header name. Note: this name does not need to be
unique; two columns in a table can have the same name.
columnIndex
- the index of the column
getEnclosedModel
protected TableModel getEnclosedModel()
Returns the enclosed tablemodel, which is wrapped by this subset table model.
- the enclosed table model, never null.
getEnd
protected int getEnd()
Returns the last row that should be visible.
- the number of the last row.
getRowCount
public int getRowCount()
Returns the number of rows in the model. A JTable
uses this method to
determine how many rows it should display. This method should be quick, as it is
called frequently during rendering.
- the number of rows in the model
getStart
protected int getStart()
Returns the start row that should be mapped to row 0 of this model.
- the first row that should be visible.
getValueAt
public Object getValueAt(int rowIndex,
int columnIndex)
Returns the value for the cell at columnIndex
and
rowIndex
.
rowIndex
- the row whose value is to be queriedcolumnIndex
- the column whose value is to be queried
- the value Object at the specified cell
isCellEditable
public boolean isCellEditable(int rowIndex,
int columnIndex)
Returns true if the cell at rowIndex
and columnIndex
is
editable. Otherwise, setValueAt
on the cell will not change the value
of that cell.
rowIndex
- the row whose value to be queriedcolumnIndex
- the column whose value to be queried
- true if the cell is editable
removeTableModelListener
public void removeTableModelListener(TableModelListener l)
Removes a listener from the list that is notified each time a change to the data
model occurs.
l
- the TableModelListener
setValueAt
public void setValueAt(Object aValue,
int rowIndex,
int columnIndex)
Sets the value in the cell at columnIndex
and rowIndex
to
aValue
.
aValue
- the new valuerowIndex
- the row whose value is to be changedcolumnIndex
- the column whose value is to be changed
