setViewSelectionModel

public void setViewSelectionModel(ListSelectionModel viewSelectionModel)

sets the view selection model. Must not be null.

Specified by:

getViewSelectionModel in interface SelectionMapper

Returns:

view selection model

setFilters

public void setFilters(FilterPipeline pipeline)

Description copied from interface: SelectionMapper

Install the new filter pipeline and map the newly filtered data towards the view.

Specified by:

isEnabled

public boolean isEnabled()

Specified by:

isEnabled in interface SelectionMapper

Returns:

true if selection mapping is active.
