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.
Attributes
Source
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 and b, even if the result is already determined after evaluating a.
Source
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. If a evaluates to false, false is returned without evaluating b.
Source
Compares two Boolean expressions and returns true if they evaluate to the same value.
Compares two Boolean expressions and returns true if they evaluate to the same value.
a == b returns true if and only if - a and b are true or - a and b are false.

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`. `

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.
Attributes
Returns
the negated expression

The semantics of value are determined at Prop creation.
The semantics of value are determined at Prop creation. See methods valueIsTrue and keyExists in object BooleanProp for examples.
Attributes
Returns
true if the current String is considered true, false otherwise

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

Compares two Boolean expressions and returns true if one or both of them evaluate to true.
Compares two Boolean expressions and returns true if one or both of them evaluate to true.
a || b returns true if and only if - a is true or - b is true or - 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. If a evaluates to true, true is returned without evaluating b.

Gets the current string value if any.
Gets the current string value if any. Will not return null: use isSet to test for existence.
Attributes
Returns
the current string value if any, else the empty string

True if the key exists in the properties map.
True if the key exists in the properties map. Note that this is not sufficient for a Boolean property to be considered true.
Attributes
Returns
whether the map contains the key
