java.lang.Object
org.apache.poi.hssf.record.formula.Ptg
org.apache.poi.hssf.record.formula.OperationPtg
org.apache.poi.hssf.record.formula.AbstractFunctionPtg
- Direct Known Subclasses:
- FuncPtg, FuncVarPtg
- public abstract class AbstractFunctionPtg
- extends OperationPtg
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

AbstractFunctionPtg
public AbstractFunctionPtg()
toString
public java.lang.String toString()
- Description copied from class:
Ptg
- Overridden toString method to ensure object hash is not printed.
This helps get rid of gratuitous diffs when comparing two dumps
Subclasses may output more relevant information by overriding this method
- Overrides:
toString
in class Ptg
