Examples of AbstractFunctionPtg

org.apache.poi.hssf.record.formula.AbstractFunctionPtg
This class provides the base functionality for Excel sheet functions There are two kinds of function Ptgs - tFunc and tFuncVar Therefore, this class will have ONLY two subclasses @author Avik Sengupta @author Andrew C. Oliver (acoliver at apache dot org)
