Public Member Functions | |
| int | compare (Object *o1, Object *o2) |
| Compare two objects o1 and o2. | |
 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 Object * | clone () |
| Return an exact copy of 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. | |

Detailed Description
Member Function Documentation
◆ compare()
Compare two objects o1 and o2.
Return a value < 0, when o1 is less than o2, a value > 0, when o1 is greater than o2, or 0, when o1 and o2 are equal.
If o1.equals(o2) (as defined in Object), compare(o1, o2) 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::Comparator.
