Class DefaultPagedTableModel

java.lang.Object
  nextapp.echo.table.AbstractTableModel
      echopoint.table.TableModelAdapter
          echopoint.table.DefaultPagedTableModel

All Implemented Interfaces:

java.util.EventListener, PagedTableModel, java.io.Serializable, nextapp.echo.table.TableModel, nextapp.echo.event.TableModelListener

public class DefaultPagedTableModel

extends TableModelAdapter

implements PagedTableModel

The DefaultPagedTableModel is a PagedTabledModel that can be used to display a subset (ie. a page worth) of data at a time from an underlying TableModel.

Notes on using DefaultPagedTableModel in a SortableTable :

The SortableTable works by wrapping the underlying data model into a SortableTableModel and then sorting it. If you use this table model, then it will only sort a page size at a time, not the whole table and then present a page size. In other words what you see on the screen at any one time will be sorted, however the total table model will not be sorted.

You can get around this by using the very related class SortablePagedTableModel. This sorts the underlying TableModel and then displays a page at a time.

Constructor Detail

DefaultPagedTableModel

public DefaultPagedTableModel(nextapp.echo.table.TableModel model)

Creates a DefaultPagedTableModel that pages over the provided TableMode with a default page size of Integer.MAX_VALUE.

Parameters:

model - - the underlying TabeModel to page

DefaultPagedTableModel

public DefaultPagedTableModel(nextapp.echo.table.TableModel model,
                              int pageSize)

Creates a DefaultPagedTableModel that pages over the provided TableModel with a default page size of pageSize.

Parameters:

model - - the underlying TabeModel to page

pageSize - - the number of rows in a page

Method Detail

previous

public void previous()

Description copied from interface: PagedTableModel

Move back a page, rolling over to getMaxPageIndex from 0

Specified by:

previous in interface PagedTableModel

See Also:

PagedTableModel.previous()

next

public void next()

Description copied from interface: PagedTableModel

Move forward a page, rolling over to 0 from getMaxPageIndex

Specified by:

next in interface PagedTableModel

See Also:

PagedTableModel.next()

getRowsPerPage

public int getRowsPerPage()

Description copied from interface: PagedTableModel

Gets the number of rows per page.

Specified by:

getRowsPerPage in interface PagedTableModel

Returns:

- the number of rows per page.

See Also:

PagedTableModel.getRowsPerPage()

setRowsPerPage

public void setRowsPerPage(int pageSize)

Description copied from interface: PagedTableModel

Sets the number of rows per page. Any integer value is fine since this just defines the viewable upper bound.

Specified by:

setRowsPerPage in interface PagedTableModel

Parameters:

pageSize - - the number of rows per page

See Also:

PagedTableModel.setRowsPerPage(int)

getPageIndex

public int getPageIndex()

Description copied from interface: PagedTableModel

Gets the current page index.

Specified by:

getPageIndex in interface PagedTableModel

Returns:

the current page index

See Also:

PagedTableModel.getPageIndex()

setPageIndex

public void setPageIndex(int pageIndex)

Description copied from interface: PagedTableModel

Sets the current page index. This method will safely roll to the max page or 0 depending on the given value being and over or under flow respectively.

Specified by:

setPageIndex in interface PagedTableModel

Parameters:

pageIndex - - the new page index

See Also:

PagedTableModel.setPageIndex(int)

getMaxPageIndex

public int getMaxPageIndex()

Description copied from interface: PagedTableModel

Gets the maximum number of pages that this model contains.

Specified by:

getMaxPageIndex in interface PagedTableModel

Returns:

the maximum number of pages that this model contains.

See Also:

PagedTableModel.getMaxPageIndex()

getTotalRowCount

public int getTotalRowCount()

Description copied from interface: PagedTableModel

Returns the total number of rows in the TableModel.

Contrasts this with the getRowCount() method.

Specified by:

getTotalRowCount in interface PagedTableModel

Returns:

the total number of rows in the TableModel.

See Also:

PagedTableModel.getTotalRowCount()

getRowCount

public int getRowCount()

Description copied from interface: PagedTableModel

In a PagedTableModel, this reports the minimum of the current rows per page or the number of rows left in the current page.

Constrast this with the original getRowCount() which reports the total number of rows in the model. This is needed to "trick" the visual Table component into thinking it sees a complete model of row data, when in fact it only sees a page.

Specified by:

getRowCount in interface PagedTableModel

Overrides:

getRowCount in class TableModelAdapter

See Also:

TableModel.getRowCount()

getValueAt

public java.lang.Object getValueAt(int column,
                                   int row)

Specified by:

getValueAt in interface nextapp.echo.table.TableModel

Overrides:

getValueAt in class TableModelAdapter

See Also:

TableModel.getValueAt(int, int)
