Hi all,
This is my first time working with a dynamically typed environment and my
first instinct is to error check all arguments. For example suppose I want
to create an object to represent an octet in an IP address (a number between
0 and 256) I would do something like this:
Object subclass: #Octet
instanceVariables: 'octetValue'
......
initialize
super initialize.
octetValue := 0.
setOctetValue: numBtw0And256
octetValue = numBtw0And256 <-------Here's where I have a problem
How do I know the numBtw0And256 is actually an integer between 0 and 256 and
not 'cat' or '3.14'?
Since I came from statically typed languages I feel like I writing a whole
bunch of error checking code along the lines of ifIsInteger: ... etc which
doesn't seem to be in the spirit of Squeak.
What am I doing wrong?
Thanks
Deech
