This method is used to compare the receiver object (this
)
with the argument object (arg0
) for equivalence
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.
A
Formatter
providing information that enables reporters to create more stylized output.An example is that specification-style suites, such as
Spec
, generate output that reads more like a specification, for instance:This output might be generated by ScalaTest's standard out reporter. Each of these lines would be taken from the
IndentedText
'sformattedText
parameter. Were this same run to be reported in HTML or in a GUI, the output would be based on therawText
and theindentationLevel
. Here's what theIndentedText
values would be for each event:InfoProvided
reported with an:IndentedText(
formattedText = "A Stack (when newly created)",
rawText = "A Stack (when newly created)",
indentationLevel = 0
)
TestSucceeded
reported with an:IndentedText(
formattedText = "- should be empty",
rawText = "should be empty",
indentationLevel = 1
)
TestSucceeded
reported with an:IndentedText(
formattedText = "- should complain when popped",
rawText = "should complain when popped",
indentationLevel = 1
)
One possible way this information could be presented in HTML, for example, is this:
A Stack (when newly created)
a localized string suitable for presenting to a user by printing it straight to an output stream
a localized string suitable for presenting to the user after in some way being indented by the value specified as the
indentationLevel
parametera zero or positive integer representing an indentation level for the indented text
