This method is used to cast the receiver object to be of type T0

This method is used to cast the receiver object to be of type T0

Note that the success of a cast at runtime is modulo Scala's erasure semantics. Therefore the expression1.asInstanceOf[String]
will throw a ClassCastException
at runtime, while the expressionList(1).asInstanceOf[List[String]]
will not. In the latter example, because the type argument is erased as
part of compilation it is not possible to check whether the contents of the list are of the requested typed.

The eq
method implements an [http://en.wikipedia.org/wiki/Equivalence_relation equivalence relation] on
non-null instances of AnyRef
:
* It is reflexive: for any non-null instance x
of type AnyRef
, x.eq(x)
returns true
.
* It is symmetric: for any non-null instances x
and y
of type AnyRef
, x.eq(y)
returns true
if and
only if y.eq(x)
returns true
.
* It is transitive: for any non-null instances x
, y
, and z
of type AnyRef
if x.eq(y)
returns true
and y.eq(z)
returns true
, then x.eq(z)
returns true
.
Additionally, the eq
method has three other properties.
* It is consistent: for any non-null instances x
and y
of type AnyRef
, multiple invocations of
x.eq(y)
consistently returns true
or consistently returns false
.
* For any non-null instance 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
).

This method is used to compare the receiver object (this

If you override this method, you should verify that your implementation remains an equivalence relation.
Additionally, when overriding this method it is often necessary to override hashCode
to ensure that objects
that are "equal" (o1.equals(o2)
returns true
) hash to the same
scala.Int
(o1.hashCode.equals(o2.hashCode)
).

This method is called by the garbage collector on the receiver object when garbage collection determines that there are no more references to 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

apply
method determines which of the passed tests to run and ignore based on tags to include and exclude passed as as class parameters.This class handles the
org.scalatest.Ignore
tag specially, in that itsapply
method indicates which tests should be ignored based on whether they are tagged withorg.scalatest.Ignore
. If"org.scalatest.Ignore"
is not passed in thetagsToExclude
set, it will be implicitly added. However, if thetagsToInclude
option is defined, and the contained set does not include"org.scalatest.Ignore"
, then only those tests that are both tagged withorg.scalatest.Ignore
and at least one of the tags in thetagsToInclude
set will be included in the result ofapply
and marked as ignored (so long as the test is not also marked with a tag other thanorg.scalatest.Ignore

set. For example, ifSlowAsMolasses
is a member of thetagsToInclude
set and a test is tagged with bothorg.scalatest.Ignore
andSlowAsMolasses
, andSlowAsMolasses
appears in thetagsToExclude
set, theSlowAsMolasses
tag will "overpower" theorg.scalatest.Ignore
tag, and the test will be filtered out entirely rather than being ignored.
