stariy95 opened a new pull request #400: CAY-2604 Specialization of property API for PK
URL: https://github.com/apache/cayenne/pull/400
 
 
   You can optionally generate PK properties like this in `cgen`:
   ```java
   public static final NumericIdProperty<Long> ARTIST_ID_PK_PROPERTY = 
       PropertyFactory.createNumericId("ARTIST_ID", "Artist", Long.class);
   ```
   
   They can be used in all cases:
   - directly in `where`
   ```java
   Artist.ARTIST_ID_PK_PROPERTY.gt(2L)
   ```
   - with `dot()` operator
   ```java
   Artist.PAINTING_ARRAY.dot(Painting.PAINTING_ID_PK_PROPERTY).eq(13)
   ```
   - to sort in db and in memory
   ```java
   Painting.PAINTING_ID_PK_PROPERTY.desc().orderList(paintings);
   ```
   - for in-memory evaluation
   ```java
   ```
