Hi guys,
currently (and probably because nobody uses them, due to some Java 1.3
habits we have), we don't use asserts to do simple things like checking
methods parameters (pre-conditions).
Should we start using them ?
+1
Just make sure, that assert isn't used in places where it's
shared/apacheds/... specific as an AssertationError is thrown in case.
See my other mail about when to use asserts or not (ie, User API should
not use them)
What about error messages? Do we need them here? If so it can blow up
the code, just imagine something like
assert ( ( value instanceof String ) || ( value instanceof byte[] ) ) :
"String or byte[] expected instead of " + value.getClass()
Yes, assert must be used with a message.
