Public Member Functions 

virtual int16_t  getInt16Value () const  
Return the numeric value of this object as an int16_t.
This may involve rounding or truncation.


virtual int32_t  getInt32Value () const  
Return the numeric value of this object as an int32_t.
This may involve rounding or truncation.


virtual int64_t  getInt64Value () const  
Return the numeric value of this object as an int64_t.
This may involve rounding or truncation.


virtual float32_t  getFloat32Value () const  
Return the numeric value of this object as a float32_t.
This may involve rounding.


virtual float64_t  getFloat64Value () const  
Return the numeric value of this object as a float64_t.
This may involve rounding.


virtual int32_t  compareTo (Object::View v) const  
Compare this object with the specified object for order.
Return a negative integer, zero, or a positive integer if this object is less than, equal to, or greater than the specified object. It is strongly recommended, but not strictly required, that


virtual bool  equals (Object::View v) const  
Return true iff the specified Object is "equal" to this Object.
This method implements an equivalence relation on Objects:
The default implementation is a reference equality comparison.


virtual size32_t  hashCode () const  
Return a hash code value for the Object.
This method is supported for the benefit of hashbased containers. The general contract of
The default implementation is identity based.
