Compares two Boolean expressions and returnstrue if they evaluate to a different value.
Compares two Boolean expressions and returnstrue if they evaluate to a different value.
a != b returnstrue if and only if -a istrue andb isfalse or -a isfalse andb istrue.

- Boolean.scala
Compares two Boolean expressions and returnstrue if both of them evaluate to true.
Compares two Boolean expressions and returnstrue if both of them evaluate to true.
a & b returnstrue if and only if -a andb aretrue.
Attributes
- Note
This method evaluates both
aandb, even if the result is already determined after evaluatinga.- Source
- Boolean.scala
Compares two Boolean expressions and returnstrue if both of them evaluate to true.
Compares two Boolean expressions and returnstrue if both of them evaluate to true.
a && b returnstrue if and only if -a andb aretrue.
Attributes
- Note
This method uses 'short-circuit' evaluation and behaves as if it was declared as
def &&(x: => Boolean): Boolean. Ifaevaluates tofalse,falseis returned without evaluatingb.- Source
- Boolean.scala
Compares two Boolean expressions and returnstrue if they evaluate to the same value.
Compares two Boolean expressions and returnstrue if they evaluate to the same value.
a == b returnstrue if and only if -a andb aretrue or -a andb arefalse.

Compares two Boolean expressions and returnstrue if they evaluate to a different value.
Compares two Boolean expressions and returnstrue if they evaluate to a different value.

Alter this property so thatvalue will be true.
Toggle the property between enabled and disabled states.
Negates a Boolean expression.
Negates a Boolean expression.
-!a results infalse if and only ifa evaluates totrue and -!a results intrue if and only ifa evaluates tofalse.
Attributes
- Returns
the negated expression

The semantics of value are determined at Prop creation. See methodsvalueIsTrue andkeyExists in object BooleanProp for examples.

- Returns
true if the current String is considered true, false otherwise

Compares two Boolean expressions and returnstrue if one or both of them evaluate to true.

Compares two Boolean expressions and returnstrue if one or both of them evaluate to true.
a || b returnstrue if and only if -a istrue or -b istrue or -a andb aretrue.
