FuncVarPtg

public FuncVarPtg(RecordInputStream in)

Creates new function pointer from a byte array usually called while reading an excel file.

FuncVarPtg

public FuncVarPtg(String pName,
          byte pNumOperands)

Create a function ptg from a string tokenised by the parser

Method Detail

writeBytes

public void writeBytes(byte[] array,
              int offset)

Description copied from class: Ptg

write this Ptg to a byte array

Specified by:

writeBytes in class AbstractFunctionPtg

getNumberOfOperands

public int getNumberOfOperands()

Description copied from class: OperationPtg

The number of operands expected by the operations

Specified by:

getNumberOfOperands in class OperationPtg

clone

public Object clone()

Specified by:

clone in class Ptg

getSize

public int getSize()

Specified by:

getSize in class AbstractFunctionPtg

toString

public 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
