-/**
- * A JFace property tester extension for the Eclipse command framework that is
- * meant for working with {@link NodeContext} instances of the Simantics
- * browsing framework.
- *
- *
- * This tester expects to receive IStructuredSelections that contain NodeContext
- * instances.
- *
- *
- * It supports testing of the following properties:
- *
- * - nodeClass - tests if the {@link NodeContext} input (see
- * {@link BuiltinKeys#INPUT}) is an instance of the class specified as an
- * argument. The class must be given as a qualified class name.
- * - deletable - for testing whether a NodeContext can be considered
- * generically deletable, see
org.eclipse.ui.edit.delete command.
- * No arguments required.
- * - modifiable - for testing whether a NodeContext can be considered
- * generically modifiable (either in-line or not), see
- *
org.eclipse.ui.edit.rename command. No arguments required.
- * - refreshable - for testing whether a NodeContext can be considered
- * generically refreshable, see
org.eclipse.ui.file.refresh
- * command. No arguments required.
