public boolean equals(Object obj)

Overrides java.lang.Object.equals.

Implements java.util.Comparator.equals.

Doc from java.util.Comparator.equals.

Indicates whether some other object is "equal to" this comparator. This method must obey the general contract of Object#equals(Object). Additionally, this method can return true only if the specified object is also a comparator and it imposes the same ordering as this comparator. Thus, comp1.equals(comp2) implies that signum(comp1.compare(o1, o2))==signum(comp2.compare(o1, o2)) for every object reference o1 and o2.

Note that it is always safe not to override Object.equals(Object). However, overriding this method may, in some cases, improve performance by allowing programs to determine that two distinct comparators impose the same order.

Parameters
obj:Object

the reference object with which to compare.

Returns:boolean

true only if the specified object is also a comparator and it imposes the same ordering as this comparator.
