Public Member Functions inherited from lout::object::Object
virtual	~Object ()
	The destructor is defined as virtual (but not abstract), so that destruction of Object's works properly.

virtual bool	equals (Object *other)
	Returns, whether two objects are equal.

virtual int	hashValue ()
	Return a hash value for the object.

virtual void	intoStringBuffer (misc::StringBuffer *sb)
	Store a textual representation of the object in a misc::StringBuffer.

const char *	toString ()
	Use object::Object::intoStringBuffer to return a textual representation of the object.

virtual size_t	sizeOf ()
	Return the number of bytes, this object totally uses.

int dw::core::CharIterator::compareTo ( lout::misc::Comparable * other )

virtual

Compare two objects c1 and c2.

return a value < 0, when c1 is less than c2, a value > 0, when c1 is greater than c2, or 0, when c1 and c2 are equal.

If also object::Object is implemented, and if c1.equals(c2), c1.compareTo(c2) must be 0, but, unlike you may expect, the reversed is not necessarily true. This method returns 0, if, according to the rules for sorting, there is no difference, but there may still be differences (not relevant for sorting), which "equals" will care about.

Implements lout::misc::Comparable.
