Method Detail

getContextMenuFacets

MenuFacets getContextMenuFacets()

Return suitable facets for a viewer context menu.

The source of the request will generally be redundant as the receiver will be able to determine which viewer is active; in any case, other considerations such as the current selection will determine the facets to be returned.

handleInvalidInput

void handleInvalidInput(STarget target,
                        java.lang.Object input)

Respond to an input to a facet which is invalid for its target.

A simple facet will generally check validity by querying a TargetCoupler attached to the target; a viewer facet by querying its SView.

Parameters:

target - exposed by the facet

input - is known to be invalid
