public Adapter caseToolBarContributions(MToolBarContributions object) {
				return createToolBarContributionsAdapter();
			}
			@Override
			public Adapter caseTrimContribution(MTrimContribution object) {
				return createTrimContributionAdapter();
			}
			@Override
			public Adapter caseTrimContributions(MTrimContributions object) {
				return createTrimContributionsAdapter();
			}
			@Override
			public Adapter caseRenderedMenuItem(MRenderedMenuItem object) {
				return createRenderedMenuItemAdapter();
			}
			@Override
			public Adapter caseOpaqueMenuItem(MOpaqueMenuItem object) {
				return createOpaqueMenuItemAdapter();
