**Methods Documentation**

### get\_style

`get_style()`

[GitHub](https://github.com/Qiskit/samplomatic/tree/main/samplomatic/samplex/nodes/sampling_node.py#L45-L50)

Return the style of this node when plotted.

### sample

*abstractmethod* `sample(registers: dict[str, VirtualRegister], rng: Generator, inputs: TensorInterface, num_randomizations: int)`

[GitHub](https://github.com/Qiskit/samplomatic/tree/main/samplomatic/samplex/nodes/sampling_node.py#L28-L43)
