Abstract methods
Compares two Boolean expressions and returns true
if they evaluate to a different value.
Compares two Boolean expressions and returns true
if they evaluate to a different value.
a != b
returns true
if and only if - a
is true
and b
is false
or - a
is false
and b
is true
.

- Boolean.scala
Compares two Boolean expressions and returns true
if both of them evaluate to true.
Compares two Boolean expressions and returns true
if both of them evaluate to true.
a & b
returns true
if and only if - a
and b
are true
.
Attributes
- Note
-
This method evaluates both
a
andb
, even if the result is already determined after evaluatinga

Compares two Boolean expressions and returns true
if both of them evaluate to true.
Compares two Boolean expressions and returns true
if both of them evaluate to true.
a && b
returns true
if and only if - a
and b
are true
.
Attributes
- Note
-
This method uses 'short-circuit' evaluation and behaves as if it was declared as
def &&(x: => Boolean): Boolean
. Ifa
evaluates tofalse
,false
is returned without evaluatingb

Compares two Boolean expressions and returns true
if they evaluate to the same value.
Compares two Boolean expressions and returns true

a == b
returns true
if and only if - a

are true
or - a
and b
are false
.

Alter this property so that value
will be true.
Toggle the property between enabled and disabled states.
Negates a Boolean expression.
Negates a Boolean expression.
- !a
results in false
if and only if a
evaluates to true
and - !a
results in true
if and only if a
evaluates to false
.

the negated expression
