org.jbox2d.collision.shapes.Shape
A shape is used for collision detection. You can create a shape however you like. Shapes used for simulation in World are created automatically when a Fixture is created. Shapes may encapsulate a one or more child shapes.

    Transform xfB = bodyB.getTransform();
    // log.debug("TransformA: "+xfA);
    // log.debug("TransformB: "+xfB);


    if (sensor) {
      Shape shapeA = m_fixtureA.getShape();
      Shape shapeB = m_fixtureB.getShape();
      touching = pool.getCollision().testOverlap(shapeA, m_indexA, shapeB, m_indexB, xfA, xfB);


      // Sensors don't generate manifolds.
      m_manifold.pointCount = 0;
