public class TaskSearchContentProvider
extends SelectableListTableContentProvider
implements ITaskSearchContentProvider

Content provider which implements Task searches and intended to be used as value for table controls in custom task inbox portlets

When using this provider class you need to configure its search query getSearchQuery() terms and call refresh() method. Most of the time this provider is extended when implementing custom task inbox by adding new search terms.

supportsAutoRefresh

public boolean supportsAutoRefresh()

Description copied from class: SelectableListTableContentProvider

Returns false

Specified by:

supportsAutoRefresh in interface IRefreshable

Overrides:

supportsAutoRefresh in class SelectableListTableContentProvider

Returns:

true when auto refresh is supported

• IRefreshable.setAutoRefresh(boolean)

setAutoRefresh

public void setAutoRefresh(boolean autoRefresh)
                    throws ContentProviderException

Description copied from interface: IRefreshable

Sets auto refresh mode on. When auto refresh mode is on, the provider calls IRefreshable.getNeedRefresh() to determine whether the refresh needs to be done before returning any result properties. If it returns true, the provider calls IRefreshable.refresh() method to updated the result properties.

Specified by:

setAutoRefresh in interface IRefreshable

Overrides:

setAutoRefresh in class SelectableListTableContentProvider

Parameters:

autoRefresh - true to turn it on

Throws:

ContentProviderException - if autorefresh is true

• IRefreshable.supportsAutoRefresh()
• IRefreshable.getNeedRefresh()
• IRefreshable.setNeedRefresh(boolean)

isAutoRefresh

Description copied from class: SelectableListTableContentProvider

Returns false

Specified by:

isAutoRefresh in interface IRefreshable

Overrides:

Specified by:

getNeedRefresh in interface IRefreshable

Overrides:

getNeedRefresh in class SelectableListTableContentProvider
