Examples of cc.redberry.core.tensor.TensorBuilder

cc.redberry.core.tensor.TensorBuilder
er of product builder.put(Tensors.parse("2")); builder.put(Tensors.parse("3")); builder.put(Tensors.parse("a")); assert TensorUtils.equals(builder.build(),Tensors.parse("6*a"));
Example 2
```
 Tensor tensor = Tensors.parse("b*a"); TensorBuilder builder = tensor.getBuilder(); //builder of product builder.put(Tensors.parse("2")); builder.put(Tensors.parse("1/2")); builder.put(Tensors.parse("a+q")); assert TensorUtils.equals(builder.build(),Tensors.parse("a+q")); //Resulting tensor class is Sum
```
There is a mimic infrastructure for tensor creation in the system, see {@link TensorFactory} for more information.
For general tensor creation use factory methods in {@link Tensors}class.
