For example, you can write:
```java
GenericDomValue<String> getVeryLongName()
GenericDomValue<String> getVeryLongName();
@PropertyAccessor("very-long-name")
GenericDomValue<String> getName()
GenericDomValue<String> getName();
```
In this case, the second method will return just the same as the first one.
