DefaultSelectionProperty

public DefaultSelectionProperty(java.lang.String currentValue,
                                java.lang.String fallbackValue,
                                java.lang.String name,
                                java.util.SortedSet<java.lang.String> possibleValues)
Construct a selection property.

Parameters:
currentValue - current value of this property, must not be null
fallbackValue - the fallback value to use, must not be null
name - the name of this property, must not be null
possibleValues - the set of possible values, must not be null and will be returned to callers, so a copy should be passed into this ctor if the caller will use this set later
