OpJoin (Apache Jena ARQ)

Methods
Modifier and Type	Method and Description
`Op`	`apply(Transform transform, Op left, Op right)`
`Op2`	`copy(Op newLeft, Op newRight)`
`static Op`	`create(Op left, Op right)` Create join - an argument of null is simply dropped so Join.create(null, op) is op and Join.create(op,null) is op.
`static Op`	`createReduce(Op left, Op right)` Create join, removing any joins with the identity table and any nulls.
`boolean`	`equalTo(Op op2, NodeIsomorphismMap labelMap)`
`String`	`getName()`
`static boolean`	`isJoinIdentify(Op op)`
`void`	`visit(OpVisitor opVisitor)`
