  2. abstract def disable(): Unit

    Alter this property so that value will be false.

  3. abstract def enable(): Unit

    Permalink

    Alter this property so that value will be true.

  4. abstract def get: String

    Permalink

    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

    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

    returns

    the old value, or null if it was unset.

    Sets the property with a value of the represented type.

    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

  12. abstract def zero: Boolean

    A value of type T for use when the property is unset.

    A value of type T for use when the property is unset. The default implementation delivers null for reference types and 0/0.0/false for non-reference types.
