Abstract methods

def !=(x: Boolean): Boolean
Implicitly added by booleanPropAsBoolean

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.

def &(x: Boolean): Boolean
Implicitly added by booleanPropAsBoolean

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.

Note

This method evaluates both a and b, even if the result is already determined after evaluating a.

def &&(x: Boolean): Boolean
Implicitly added by booleanPropAsBoolean

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.

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.

def ==(x: Boolean): Boolean
Implicitly added by booleanPropAsBoolean

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.

def ^(x: Boolean): Boolean
Implicitly added by booleanPropAsBoolean

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.

def disable(): Unit

Alter this property so that value will be false.

Alter this property so that value will be false.

def enable(): Unit

Alter this property so that value will be true.

Alter this property so that value will be true.

def toggle(): Unit

Toggle the property between enabled and disabled states.

Toggle the property between enabled and disabled states.

Implicitly added by booleanPropAsBoolean

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.

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.

Returns

true if the current String is considered true, false otherwise

def |(x: Boolean): Boolean
Implicitly added by booleanPropAsBoolean

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.

Note

This method evaluates both a and b, even if the result is already determined after evaluating a.

def ||(x: Boolean): Boolean
Implicitly added by booleanPropAsBoolean

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.

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.

Inherited methods

def clear(): Unit

Removes the property from the underlying map.

Removes the property from the underlying map.

Inherited from
Prop
def get: String

Gets the current string value if any.

Gets the current string value if any. Will not return null: use isSet to test for existence.

Returns

the current string value if any, else the empty string

Inherited from
Prop

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.

Returns

whether the map contains the key

Inherited from
Prop
def key: String

The full name of the property, e.g., "java.awt.headless".

The full name of the property, e.g., "java.awt.headless".

Inherited from

Some(value) if the property is set, None otherwise.

Some(value) if the property is set, None otherwise.

def set(newValue: String): String

Sets the property.

Sets the property.

Value Params
newValue

the new string value

Returns

the old value, or null if it was unset.

def setValue[T1 >: Boolean](value: T1): Boolean

Sets the property with a value of the represented type.
