Examples of ratpack.util.internal.TypeCoercingProperties.asClass()

ratpack.util.internal.TypeCoercingProperties.asClass()
Gets a property value as a Class. The property value should be a fully-qualified class name that can be loaded via the ClassLoader passed to the constructor. The class should be an instance of the type parameter – typically an interface. @param key the property key. @param type the expected type of the Class, typically the interface it should implement. @return a Class or null if the property does not exist. @throws ClassNotFoundException if no Class is found matching the name from the property value. @throws ClassCastException if a Class is loaded but it does not implement the type interface.
