Constructor Detail

NumberPtg

public NumberPtg(RecordInputStream in)
Create a NumberPtg from a byte array read from disk


NumberPtg

public NumberPtg(java.lang.String value)
Create a NumberPtg from a string representation of the number Number format is not checked, it is expected to be validated in the parser that calls this method.

Parameters:
value - : String representation of a floating point number

NumberPtg

public NumberPtg(double value)
Method Detail

getValue

public double getValue()

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 Ptg

getSize

public int getSize()
Specified by:
getSize in class Ptg
Returns:
the encoded length of this Ptg, including the initial Ptg type identifier byte.

toFormulaString

public java.lang.String toFormulaString()
Description copied from class: Ptg
return a string representation of this token alone

Specified by:
toFormulaString in class Ptg

isBaseToken

public boolean isBaseToken()
Specified by:
isBaseToken in class Ptg
Returns:
false if this token is classified as 'reference', 'value', or 'array'

getDefaultOperandClass

public final byte getDefaultOperandClass()
Specified by:
getDefaultOperandClass in class Ptg

toString

public final 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
