The usual “new” and “initialize” singleton methods are defined in the ResKeyList class. These methods have no arguments. The class member method “clone” has no argument and returns a copy of the object.
The user can fill its one ResKeyList object with the “insert” method. This method takes one Array Argument with between 1 and 4 elements corresponding to the element identifier, the node identifier, the layer identifier and the sub-layer identifier. Each element can be a String or an integer.
