Method Detail

getRefreshPageBinding

public MethodBinding getRefreshPageBinding()

Parameterless method that refreshes page data service

Returns:

method binding to the refresh method impl.

setRefreshPageBinding

public void setRefreshPageBinding(MethodBinding refreshPageDataBinding)

setPageRowIndex

public void setPageRowIndex(int row)

Description copied from interface: IPageableTableContentProvider

Sets the page starting row index.

Specified by:

setPageRowIndex in interface IPageableTableContentProvider

Parameters:

row - row index

See Also:

PageableTableContentProvider.getPageRowIndex()

getPageRowIndex

public int getPageRowIndex()

Page starting row index. Should be bound to the table control first property and used as an input parameter to the page service provider.

Specified by:

getPageRowIndex in interface IPageableTableContentProvider

Returns:

row index

getRowCount

public int getRowCount()

Return number of rows in this virtual table. Not all rows can be loaded. Can be -1 if unknown. The number of rows becomes known when paging service returns empty set of data of when the client assigns it using PageableTableContentProvider.setRowCount(int) method.

Specified by:

getRowCount in interface ITableContentProvider

Overrides:

getRowCount in class ListTableContentProvider

Returns:

-1 if unknown or actual number of rows.

See Also:

DataModel.getRowCount()

setRowCount

public void setRowCount(int rowCount)

Allow paging service to set known row count. Setting -1 will force the provider to call the service until it gets empty set of data.

Parameters:

rowCount - known row count or -1 if unknown

refresh

public void refresh()

Resets internal cache, rowCount and pageRowIndex. This will force the provider to call the paging service again when the client control requests first row.

Specified by:

refresh in interface IRefreshable

Overrides:

refresh in class SelectableListTableContentProvider

isRowAvailable

public boolean isRowAvailable()

When row is not loaded and row count is not known or row index is less than known row count, call the paging service and load the data.

Specified by:

isRowAvailable in interface ITableContentProvider

Overrides:

isRowAvailable in class ListTableContentProvider

Returns:

true if row is already loaded and just loaded after the paging service call

See Also:

DataModel.isRowAvailable()

refreshPage

protected void refreshPage()

Refreshes the associated page data provider. The typical implementation is to assign paging service input parameters based on pageRowIndex, call the service and reassign return data back. Return data may be array, list or table provider and may define rowCount as well. Default implemention calls PageableTableContentProvider.getRefreshPageBinding() method if not null

loadPageData

protected void loadPageData()

Loads current page data into inernal cache

getTable

public ITableContentProvider getTable()

Return table provider for page data. Will be this if PageableTableContentProvider.setList(List) or {@link #setArray(Object[]) is set.

Returns:

ITableContentProvider for specified page

setTable

public void setTable(ITableContentProvider tableProvider)

Sets external ITableContentProvider instance to use for page data

Parameters:

tableProvider - table provider

getArray

public Object[] getArray()

Description copied from class: ListTableContentProvider

Returns (a copy of the) array previously set as the source

Overrides:

getArray in class ListTableContentProvider

Returns:

null if array was not set

getList

public List getList()

Description copied from class: SelectableListTableContentProvider

Returns wrapped list object

Overrides:

getList in class SelectableListTableContentProvider

Returns:

null if not set

setArray

public void setArray(Object[] array)

Description copied from class: ListTableContentProvider

Creates a list object out of source array and sets it as the source

Overrides:

setArray in class ListTableContentProvider

Parameters:

array - the array of objects

setList

public void setList(List list)

Description copied from class: SelectableListTableContentProvider

Sets a list to wrap

Overrides:

setList in class SelectableListTableContentProvider

Parameters:

list - a list
