This class implements a simple proxy that forwards all calls to
the public, non-final methods defined in class Any
to another
object self. Those methods are:
def hashCode(): Int
def equals(other: Any): Boolean
def toString(): String
Note: forwarding methods in this way will most likely create an asymmetric equals method, which is not generally recommended.

Compares the receiver object (this
) with the argument object (that
) for equivalence.
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 type Any
, x.equals(x)
should return true
.
- It is symmetric: for any instances x
and y
of type Any
, x.equals(y)
should return true
if and
only if y.equals(x)
returns true
.
- It is transitive: for any instances x
, y
, and z
of type Any
if x.equals(y)
returns true
and
y.equals(z)
returns true
, then x.equals(z)
should return true
.
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)
).
- Value parameters:
- that
the object to compare against this object for equality.
- Returns:
true
if the receiver object is equivalent to the argument;false
otherwise.- Definition Classes

Calculate a hash code value for the object.
Calculate a hash code value for the object.
The default hashing algorithm is platform dependent.
Note that it is allowed for two objects to have identical hash codes (o1.hashCode.equals(o2.hashCode)
) yet
not be equal (o1.equals(o2)
returns false
). A degenerate implementation could always return 0
.
However, it is required that if two objects are equal (o1.equals(o2)
returns true
) that they have
identical hash codes (o1.hashCode.equals(o2.hashCode)
). Therefore, when overriding this method, be sure
to verify that the behavior is consistent with the equals
method.
