java.lang.Object structure.StructCollection<ELTTYPE>
public class StructCollection<ELTTYPE>
This utility class converts a Structure to a Collection.
Users are advised to make use of the values
method
that is part of every Structure
that returns a Collection
.
This class is necessary because there are certain basic differences in the interfaces of the two classes.
This class works provides a facade: methods of the Collection interface are directly referred to the base Structure, or simple code supports the interface.
Example Usage:
public static void main(String[] argv){
Structure struct = new Vector();
for(int i = 0; i < argv.length; i++) struct.add(argv[i]);
Collection collect = new StructCollection(struct)
;
}
