 \subsection{Template Method Pattern}
-TBD
+Due to the extendibility of Jackson, it is of no surprise that the template
+method pattern is used extensively to create a class hierarchy that provides
+rich interfaces while maintaining behavioural flexibility.  \textit{Pattern4}
+correctly detects several instances of the pattern, namely
+\textbf{JsonStreamContext}, \textbf{JsonGenerator}, \textbf{type.ResolvedType},
+\textbf{JsonParser}, \textbf{base.ParserBase}, \textbf{base.GeneratorBase},
+\textbf{base.ParserMinimalBase}. All these classes implement several concrete
+\texttt{public} methods throwgh the use of \texttt{protected abstract} methods.
+Although the concrete (i.e. the template) methods are usually not vary complex
+(as the pattern example shown in class), they still follow the principles of the
+template method pattern. We show as an example some template methods found in
+\textbf{base.ParserBase}:
+
+\begin{lstlisting}[caption=Template method \texttt{void close()} and step
+methods \texttt{void \_closeInput()} and \texttt{void \_releaseBuffers()} in
+\textbf{base.ParserBase}., language=java]
+@Override public void close() throws IOException {
+    if (!_closed) {
+        // 19-Jan-2018, tatu: as per [core#440] need to ensure no more data
+        //  assumed available
+        _inputPtr = Math.max(_inputPtr, _inputEnd);
+        _closed = true;
+        try {
+            _closeInput();
+        } finally {
+            // as per [JACKSON-324], do in finally block
+            // Also, internal buffer(s) can now be released as well
+            _releaseBuffers();
+        }
+    }
+}
+
+protected abstract void _closeInput() throws IOException;
+
+protected void _releaseBuffers() throws IOException { 
+  /* implementation omitted */
+}
+\end{lstlisting}
+
+Here the pattern is slightly modified by providing a default implementation of
+\texttt{void \_releaseBuffers()}. In this case, child classes occasionally
+override the method with a body first calling \texttt{super()} and then adding
+additional buffer release code after.
+
