def equals(that: Any): Boolean
Compares the receiver object ( this
) with the argument object ( that
) for
equivalence.
Any implementation of this method should be an equivalence relation :
- It is reflexive: for any instance
x
of typeAny
,x.equals(x)
should returntrue
. - It is symmetric: for any instances
x
andy
of typeAny
,x.equals(y)
should returntrue
if and only ify.equals(x)
returnstrue
. - It is transitive: for any instances
x
,y
, andz
of typeAny
ifx.equals(y)
returnstrue
andy.equals(z)
returnstrue
, thenx.equals(z)
should returntrue
.
If you override this method, you should verify that your implementation remains
an equivalence relation. Additionally, when overriding this method it is usually
necessary to override hashCode
to ensure that objects which are “equal” (
o1.equals(o2)
returns true
) hash to the same scala.Int. (
o1.hashCode.equals(o2.hashCode)
).
- that
- the object to compare against this object for equality.
- returns
true
if the receiver object is equivalent to the argument;false
otherwise.
