com.hp.hpl.jena.sparql.algebra.op.OpBase

com.hp.hpl.jena.sparql.algebra.op.Op1

com.hp.hpl.jena.sparql.algebra.op.OpLabel

All Implemented Interfaces:

Op, Named, PrintSerializable, Printable

public class OpLabel
extends Op1

Do-nothing class that means that tags/labels/comments can be left in the algebra tree. If serialized, toString called on the object, reparsing yields a string. Can have zero one one sub ops.
