Tests whether the argument (

).Tests whether the argument (
that
) is a reference to the receiver object (this
).The
eq
method implements an equivalence relation on nonnull instances ofAnyRef
, and has three additional properties: It is consistent: for any nonnull instances
x
andy
of typeAnyRef
, multiple invocations ofx.eq(y)
consistently returnstrue
or consistently returnsfalse
.  For any nonnull instance
x
of typeAnyRef
,x.eq(null)
andnull.eq(x)
returnsfalse
. null.eq(null)
returnstrue
.
When overriding the
equals
orhashCode
methods, it is important to ensure that their behavior is consistent with reference equality. Therefore, if two objects are references to each other (o1 eq o2
), they should be equal to each other (o1 == o2
) and they should hash to the same value (o1.hashCode == o2.hashCode
). returns
true
if the argument is a reference to the receiver object;false
otherwise.

Should only be called after all known nonprimitive types have been excluded. This method won't dispatch anywhere else after checking against the primitives to avoid infinite recursion between equals and this on unknown "Number" variants.
Additionally, this should only be called if the numeric type is happy to be converted to Long, Float, and Double. If for instance a BigInt much larger than the Long range is sent here, it will claim equality with whatever Long is left in its lower 64 bits. Or a BigDecimal with more precision than Double can hold: same thing. There's no way given the interface available here to prevent this error.

which are accessible in all Scala compilation units without explicit qualification or imports.Notable packages include:
scala.collection
and its subpackages contain Scala's collections frameworkscala.collection.immutable

Additional parts of the standard library are shipped as separate libraries. These include:

Identifiers in the scala package and the
scala.Predef

List
is an alias forscala.collection.immutable.List
.Other aliases refer to classes provided by the underlying platform. For example, on the JVM,
String
is an alias forjava.lang.String
.
