Subject Variations of 'like'
Date Fri, 21 Nov 2014 12:19:21 GMT
Another API idea that I just had while analyzing boilerplate code of the client Cayenne apps.
An argument to Property.like(..) (or second argument to ExpressionFactory.likeExp(..)) requires
a full pattern to match against. So people would often write their own utility code to wrap
a String in "%" signs. Cayenne can easily take care of this via the following methods:


Property.contains(string);
// same as Property.like("%" + string + "%");

Property.startsWith(string);
// same as Property.like(string + "%");

Property.endsWith(string);
// same as Property.like("%" + string);

In addition to saving the user from String concatenation, these new methods can do proper
symbol escaping, making "like" much safer to use.
