Hi there,
In this case you've created @aObjects as a class instance variable, which
means it's not visible to instance methods. Add a constructor to set it up
instead:
class CLWindow
def initialize
@aObjects = Array.new
end
def add_object
puts @aObjects.length
end
end
cl = CLWindow.new
cl.add_object
=> 0
Also watch out in your getObject method, it looks like you're using aObjects
- which will now be a local method variable - instead of @aObjects.

Hi all,
I receive an error stating that the method 'length' is not recognized. I
am using it at an array that exists within a class.
The error occurs at the line stating: nLength = @aObjects.length within
the method of addObject(object)
I think that it doesn't see @aObjects as an array, but I can't figure out
why.
Any help?
Code:
class CLWindow
@strWindowName
@aObjects = Array.new
def setWindowName(windowname)
@strWindowName = windowname
end
def getWindowName()
return @strWindowName
end
def addObject(object)
nLength = @aObjects.length
@aObjects.insert(nLength, object)
end
def getObject(strName, strType, strFysDes)
i = 0;
if (strName!='') then
while
(aObjects[i].getObjectName()!=strName)and(i<=aObjects.length)
i=i+1
end
else
if (strType!='') then
while
(aObjects[i].getObjectType()!=strType)and(i<=aObjects.length)
i=i+1
end
else
if (strFysDes!='') then
while
(aObjects[i].getFysicalDescription()!=strFysDes)and(i<=aObjects.length)
i=i+1
end
else
return -1
end
end
end
if (i>aObjects.length) then
return -1
else
return aObjects[i]
end
end
end
