Hi folks!
Today, at work, a friend ask me about a method in TestResource because he thought it was a bug. We look at it, and for us, it could be a bug. So, I ask to you.
See TestResource class side isAvailable
------------------------
isAvailable
^self current notNil and: [self current isAvailable]
------------------------
the first part (self current notNil) ALWAYS return true because of the implementation of self current:
------------------------
current
current isNil
ifTrue: [current := self new].
^current
-------------------------
The second part too. Because the implementation of self available (object side method):
-------------------------
isAvailable
"override to provide information on the
readiness of the resource"
^true
-------------------------
Ok, you can override and change this method in subclasses, however, the first part is ALWAYS true.
Is this correct ? or isAvailable should be:
isAvailable
^ self current isAvailable
Thanks!
Mariano
