Method Detail

compareTo

public double compareTo(org.eclipse.emf.ecore.EObject leftElement,
                        org.eclipse.emf.ecore.EObject rightElement)

Compare the children of both elements.
Only direct children are considered at the comparison. Therefore the comparison determines the matching-values of previous rounds for the tuples oft the child-elements.

Specified by:

compareTo in class Comparator

Parameters:

leftElement - the left element for the comparison of the containment.

rightElement - the right element for the containment-comparison.

Returns:

This method must return a double value between 0 and 1.0
1.0 stands for a total matching without any differences and 0 means that there are no commonalities.
