Class PathBase<T,P extends Path<T>>

java.lang.Object
org.aksw.commons.path.core.PathBase<T,P>
Type Parameters:
T -
P -
All Implemented Interfaces:
Serializable, Comparable<Path<T>>, Iterable<Path<T>>, Path<T>
Direct Known Subclasses:
PathJson, PathStr
public class PathBase<T,P extends Path<T>> extends Object implements Path<T>, Serializable
Generic base implementation of the path interface. Internally keeps a flag for whether the path is absolute and a list of path segments. All methods of this class are implemented against the PathOps interface. Complex or verbose type expressions can be abstracted by extending this class as sketched below. 
 class MyPath extends PathBase<ComplexTypeExpression, MyPath> {
    MyPath(PathOps<T, P> pathOps, boolean isAbsolute, List segments) {
      super(pathOps, isAbsolute, segments);
    }
 }

 class MyPathOps implements PathOps {
   MyPath newPath(boolean isAbsolute, List segments) {
     return new MyPath(this, isAbsolute, segments);
   }

   // Implement remaining methods
 }
