Equivalent to x.hashCode

For numerics, it returns a hash value which is consistent
with value equality: if two value type instances compare
as true, then ## will produce the same hash value for each
of them.
For null

throws a
NullPointerException
.

Cast the receiver object to be of type T0
.
Cast the receiver object to be of type T0

will not.

not possible to check whether the contents of the list are of the requested type.

Create a copy of the receiver object.

).
Tests whether the argument (arg0
) is a reference to the receiver object (this

The eq
method implements an equivalence relation on
non-null instances of AnyRef
, and has three additional properties:
x
and y
of type AnyRef
, multiple invocations of
x.eq(y)
consistently returns true
or consistently returns false
.x
of type AnyRef
, x.eq(null)
and null.eq(x)
returns false
.null.eq(null)
returns true
. When overriding the equals
or hashCode
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
).

A collection of decorators that allow to convert between Scala and Java collections using
asScala
andasJava
methods.The following conversions are supported via
asJava
,asScala
scala.collection.Iterable
<=>java.lang.Iterable
scala.collection.Iterator
<=>java.util.Iterator
scala.collection.mutable.Buffer
<=>java.util.List
scala.collection.mutable.Set
<=>java.util.Set
scala.collection.mutable.Map
<=>java.util.Map
scala.collection.mutable.ConcurrentMap
<=>java.util.concurrent.ConcurrentMap
In all cases, converting from a source type to a target type and back again will return the original source object, e.g.
The following conversions also are supported, but the direction Scala to Java is done my a more specifically named method:
asJavaCollection
,asJavaEnumeration
,asJavaDictionary
.scala.collection.Iterable
<=>java.util.Collection
scala.collection.Iterator
<=>java.util.Enumeration
scala.collection.mutable.Map
