\subsection{Detailed Description}
\subsubsection*{template$<$typename PP, typename MP, typename PAT\_\-ST, template$<$ typename, typename, typename $>$ class CC$>$ class tokenizer$<$ TREE\_\-PATTERN $>$}

Tree tokenizer class by partial specialization of the generic tokenizer class. 

the template argument is instantiated with a pattern that has directed, acyclic, indegree\_\-lte\_\-one pattern property(tree), MINING\_\-PROPS type of mining property, ST type of pattern storage and CC type of canocial code.
