A method that should be called from every well-designed equals method that is open to be overridden in a subclass. See Programming in Scala, Chapter 28 for discussion and design.
- Value parameters:

the value being probed for possible equality
- Returns:
true if this instance can possibly equal
that
, otherwise false- Definition Classes

Note: testing for erasure here is important, as it is many times faster than <:< and rules out most comparisons.

A ClassTag[T] can serve as an extractor that matches only objects of type T.
A ClassTag[T] can serve as an extractor that matches only objects of type T.
The compiler tries to turn unchecked type tests in pattern matches into checked ones
by wrapping a (_: T)
type pattern as ct(_: T)
, where ct
is the ClassTag[T]
instance.
Type tests necessary before calling other extractors are treated similarly.
SomeExtractor(...)
is turned into ct(SomeExtractor(...))
if T
in SomeExtractor.unapply(x: T)
is uncheckable, but we have an instance of ClassTag[T]
.

Concrete fields
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.
- Returns:
the hash code value for this object.
