Method Detail

compare

public int compare(java.lang.Object o1,
                   java.lang.Object o2)
This compares two Events. Comparison order: UriTriple, happened, user, eventType This way we rule out most elements immediatelly, so remaining few can be processed sequentially.

Specified by:
compare in interface java.util.Comparator

equals

public boolean equals(java.lang.Object obj)
Description copied from interface: java.util.Comparator
Return true if the object is equal to this object. To be considered equal, the argument object must satisfy the constraints of Object.equals(), be a Comparator, and impose the same ordering as this Comparator. The default implementation inherited from Object is usually adequate.
