This method is used to compare the receiver object (this
)
with the argument object (arg0
) for equivalence.
The default implementations of this method is an equivalence relation:
x
of type Any
,
x.equals(x)
should return true
.x
and y
of type
Any
, x.equals(y)
should return true
if and only
if y.equals(x)
returns true
.x
, y
, and z
of type AnyRef
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 often necessary to
override hashCode
to ensure that objects that are
"equal" (o1.equals(o2)
returns true
)
hash to the same Int
(o1.hashCode.equals(o2.hashCode)
).
the object to compare against this object for equality.
true
if the receiver object is equivalent to the argument; false
otherwise.
Returns a hash code value for the object
Returns 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 a string representation of the object
Returns a string representation of the object.
The default representation is platform dependent.

Creates a new Conductor
, passes the Conductor
to the
specified test function, and ensures that conduct
gets invoked
on the Conductor
.
After the test function returns (so long as it returns normally and doesn't
complete abruptly with an exception), this method will determine whether the
conduct
method has already been called (by invoking
conductingHasBegun
on the Conductor
). If not,
this method will invoke conduct
to ensure that the
multi-threaded test is actually conducted.
Trait that can pass a new
Conductor
fixture into tests, for use in suites such asMultipleFixtureFunSuite
orMultipleFixtureSpec
, which facilitate writing tests that take different types of fixtures.Here's an example of the use of this trait to test the

concurrency abstraction fromjava.util.concurrent
