Method Detail

getRowCount

public int getRowCount()

Specified by:

getRowCount in interface TableModel

getColumnCount

public int getColumnCount()

Specified by:

getColumnCount in interface TableModel

getValueAt

public Object getValueAt(int rowIndex,
                         int columnIndex)

Specified by:

getValueAt in interface TableModel

getCellSpanAt

public CellSpan getCellSpanAt(int rowIndex,
                              int columnIndex)

Description copied from interface: SpanModel

Gets the cell span at the specified row and column. To avoid creating many instances of CellSpan, you can return the same instance by changing its values only. For example, the code below is a good example.

 private final CellSpan span = new CellSpan(0,0,1,1);
 public CellSpan getCellSpanAt(int row, int col) {
     span.setRow(...);
     span.setColumn(...);
     span.setRowSpan(...);
     span.setColumnSpan(...);
     return span;
 }
 

For performance consideration, if the cell span has 1 row span and 1 column span, it is better to return null instead of new CellSpan(row, column, 1, 1).

Specified by:

getCellSpanAt in interface SpanModel

Parameters:

rowIndex - the row index.

columnIndex - the column index.

Returns:

CellSpan object.

isCellSpanOn

public boolean isCellSpanOn()

Description copied from interface: SpanModel

Checks if the span is on. The CellSpanTable will ignore all the CellSpans defined in this model if this method returns false.

Since 3.5.12, please fire table data changed event if the returned value of this method is changed. Otherwise the CellSpanTable might still use the cached value to improve performance.

Specified by:

isCellSpanOn in interface SpanModel

Returns:

true if span is on. Otherwise false.

getCellStyleAt

public final CellStyle getCellStyleAt(int rowIndex,
                                      int columnIndex)

Gets the cell style at the specified cell. This method is final. Please use PivotDataModel.setCellStyleProvider(PivotCellStyleProvider) to provide cell style for HeaderTable.

Specified by:

getCellStyleAt in interface StyleModel

Parameters:

rowIndex -

columnIndex -

Returns:

the cell style at the specified cell.

isCellStyleOn

public final boolean isCellStyleOn()

Description copied from interface: StyleModel

Checks if the style is on. The CellStyleTable will ignore all the CellStyles defined in this model if this method returns false.

Specified by:

isCellStyleOn in interface StyleModel

Returns:

true if style is on. Otherwise false.

getPivotDataModel

public IPivotDataModel getPivotDataModel()

Gets the PivotDataModel.

Returns:

the PivotDataModel.

getFieldAt

public PivotField getFieldAt(int rowIndex,
                             int columnIndex)

Gets the pivot field associated with the cell.

Parameters:

rowIndex - the row index

columnIndex - the column index

Returns:

the pivot field associated with the cell. It could return null for certain cells when there are more than one data fields.
