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

virtual Object *	clone ()
	Return an exact copy of the object.

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.

Private Member Functions
	TextIterator (TextIterator &it)

Private Attributes
const char *	text
	May be NULL, in this case, the next is skipped.

Member Function Documentation

◆ compareTo()

int dw::core::TextIterator::compareTo ( lout::object::Comparable * other )

virtual

Compare two objects, this and other.

Return a value < 0, when this is less than other, a value > 0, when this is greater than other, or 0, when this and other are equal.

If c1.equals(c2) (as defined in Object), 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::object::Comparable.
