------------------------------
Summary: Widen types before performing in-memory evaluation of
qualifiers using j.l.Number subclasses
Key: CAY-1987
URL: https://issues.apache.org/jira/browse/CAY-1987
Project: Cayenne
Issue Type: Improvement
Components: Core Library
Affects Versions: 4.0.M2
Environment: trunk
Reporter: John Huss
Priority: Minor
There is a difference in the behavior of Expressions evaluated in memory versus
by the database when comparing attributes with a type like java.lang.Short with
a literal of type java.lang.Integer. In memory Short(1) != Integer(1), but
they are equal in the database. Using a less strict comparison in memory would
be preferable.
I figured there would be an open source implementation of this somewhere that
calculates the widest type and compares the two values, but I couldn't find
one. I imagine you could just call number.doubleValue() and compare that, but
that seems sketchy.
If you think this is worth doing I could try writing an implementation.
