    "description": "The `CleanupVisitor` is a class in the SOFA framework under the `sofa::simulation` namespace, inheriting from the `Visitor` class. Its primary role is to facilitate the cleanup process by traversing and cleaning up objects within the scene graph of a simulation. It ensures that objects are properly cleaned up, even if their removal affects the structure of the node list during the cleanup process.\n\n### Interactions with Other Components:\nThe `CleanupVisitor` interacts with nodes in the SOFA scene graph through methods such as `processNodeTopDown`, which is responsible for visiting each node and cleaning up objects within it. The method `processNodeBottomUp` exists but does not perform any actions in this implementation.\n\n### Practical Usage Guidance:\nThe component is typically used internally by the framework during cleanup phases of a simulation to ensure that all resources are properly released and no memory leaks occur. It iterates through each node and its objects, invoking their `cleanup()` method to finalize resource deallocation. The process ensures that modifications to the graph structure do not interfere with the cleaning sequence."

Instead, it ensures that objects within the scene graph are properly cleaned up and finalized.\n\n### Constitutive or Kinematic Laws Involved:\n- The `CleanupVisitor` does not involve any constitutive or kinematic laws (e.g., strain measures, stress tensors, hyperelastic potentials, damping models). It is a utility class for managing the cleanup of objects within the scene graph.\n\n### Role in the Global FEM Pipeline:\n- **Assembly:** Not applicable.\n- **Time Integration:** Not applicable.\n- **Nonlinear Solve:** Not applicable.\n- **Linear Solve:** Not applicable.\n- **Constraint Handling:** Not directly involved, but ensures that constraints and related objects are properly cleaned up.\n- **Mapping:** Not applicable.\n\n### Numerical Methods or Discretization Choices:\n- The `CleanupVisitor` does not encode any specific numerical methods or discretization choices. It is a utility class for managing the cleanup process within the scene graph, ensuring that all resources are properly released and no memory leaks occur.\n\n### Fit into the Broader Variational / Lagrangian Mechanics Framework:\n- The `CleanupVisitor` ensures that objects are cleaned up correctly at the end of a simulation. This is crucial for maintaining the integrity of the simulation framework but does not directly influence any variational or Lagrangian mechanics computations."
