Class UrlEntityInjector
java.lang.Object
to.etc.domui.injector.PropertyInjector
to.etc.domui.injector.UrlEntityInjector
public class UrlEntityInjector
- extends PropertyInjector
This property injector takes the named URL parameter as a string. It does a lookup of the entity specified
in the MetaData and locates it's ID property. The URL parameter string is then converted to the type of that
primary key using the ConverterRegistry's URL converters. Finally it issues a LOOKUP of the entity using that
PK. This converter accepts the special value "NEW"; when that is present it constructs a new instance of the
entity.
