Detailed Description

The abstract class Number is the superclass of classes BigDecimal, BigInteger, Byte, Double, Float, Integer, Long, and Short.

Subclasses of Number must provide methods to convert the represented numeric value to byte, double, float, int, long, and short.

Constructor & Destructor Documentation

java::lang::Number::Number (  ::xmog_dummy  _use_java_ctor,
::xmog_localenv *  p_xenv = NULL,
xmog_flags  f_xflags = xmogDefaultFlags
) 
 

Parameters:
_use_java_ctor indicates that you want to delegate to a Java constructor whose natural proxy conflicts with a C++ requirement.
p_xenv the local call environment. The default value is NULL.
f_xflags the flags that allow control over the reference type and other internal matters. The default value is xmog_base::GLOBAL.
