LegacyViewerContributionExpression

final public class LegacyViewerContributionExpression extends WorkbenchWindowExpression (Code)

An expression that can control the activation of a handler derived from a viewer contribution. The viewer contribution is linked to a menu with a particular identifier, as well as some other criteria. This expression checks the target menu id, and contains a child expression for the other criteria.

This class is not intended for use outside of the org.eclipse.ui.workbench plug-in.
