Examples of cc.redberry.core.tensor.Tensor.equivalent()

cc.redberry.core.tensor.Tensor.equivalent()
This method returns simplified equivalent of this tensor. It is obtaining by overriding method in inheritors. For example if Product consist only of one element, this method returns this element. Another example: if Sum is empty, method returns zero. By default, this method returns this. @see Product#equivalent() @see Sum#equivalent() @return simplified equivalent of this tensor

        TensorIterator it = factors.iterator();
        Tensor equivalent;
        Tensor current;
        while (it.hasNext()) {
            current = it.next();
            equivalent = current.equivalent();
            if (current != equivalent)
                it.set(equivalent);
        }
        return pairProduct(Transformations.calculateNumbers(factors), term.equivalent());
