[Boost-users] Disabling Tokenizer in Derived Classes - after their constructors have been executed.

Hi, I have boost tokenizer and its iterator stored in my base class. The tokenizer got initialized with a const std::string&. I do the tokenization in my base class and provide the iterator, pointing to the first token, to the derived classes - but only to be used in their constructors. After the derived class constructor has been executed, the tokenizer and its iterator should not remain available - what can I do to accomplish that? Best regards, Asif
