java.lang.Object

it.uniroma2.sag.kelp.data.representation.structure.StructureElementFactory

public class StructureElementFactory
extends Object

This class implement a Factory Design pattern to instantiate StructureElement given a string representing it.

Note:When a new class implementing a StructureElement is added, it should be annotated with @JsonTypeName("NEW_TYPE") that is used to determine the new element. The input String will be in the form NEW_TYPE##struct_content
