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.
