Re: otcl c++ variable binding.

[Kannan Varadhan <kannan@ISI.EDU>]

Hi Karu,

The C++ variable, duplicate_, must be a member variable of the class.
Likewise, the OTcl variable, duplicate_, is an instance variable
of the OTcl class.  You can access this instance variable only through
an object instance in the class Classifier/MH.  So, your code should read

	set cmh [new Classifier/MH]
	$cmh set duplicate_

to access this instance variable.

Additional details of all of this binding can be found in
the documentation, at http://www-mash.cs.berkeley.edu/ns/nsDoc.tar.gz.

Hope this helps,


Kannan
