getNumber
public java.lang.Number getNumber()
Returns the number.- Returns:
- the number
-
setNumber
public void setNumber(java.lang.Number number)
Sets the number.- Parameters:
number
- the number
-
doubleOut
public static java.lang.String doubleOut(java.lang.Double doubleDown)
Output a Double value to a string suitable for PDF.- Parameters:
doubleDown
- the Double value- Returns:
- the value as a string
-
doubleOut
public static java.lang.String doubleOut(double doubleDown)
Output a double value to a string suitable for PDF (6 decimal digits).- Parameters:
doubleDown
- the double value- Returns:
- the value as a string
-
doubleOut
public static java.lang.String doubleOut(double doubleDown, int dec)
Output a double value to a string suitable for PDF. In this method it is possible to set the maximum number of decimal places to output.- Parameters:
doubleDown
- the Double valuedec
- the number of decimal places to output- Returns:
- the value as a string
-
doubleOut
public static java.lang.StringBuffer doubleOut(double doubleDown, int dec, java.lang.StringBuffer buf)
Append a double value to a string buffer suitable for PDF. In this method it is possible to set the maximum number of decimal places to output.- Parameters:
doubleDown
- the Double valuedec
- the number of decimal places to outputbuf
- the string buffer to which double is formatted (appended)- Returns:
- the string buffer
-
toPDFString
protected java.lang.String toPDFString()
This method returns a String representation of the PDF object. The result is normally converted/encoded to a byte array by toPDF(). Only use this method to implement the serialization if the object can be fully represented as text. If the PDF representation of the object contains binary content use toPDF() or output(OutputStream) instead. This applies to any object potentially containing a string object because string object are encrypted and therefore need to be binary.- Overrides:
toPDFString
in classPDFObject
- Returns:
- String the String representation
