# reset_flags Enumeration

[flow_graph.reset_flags]

A `reset_flags` enumeration represents flags that can be passed to the `graph::reset()` function.

    // Defined in header <oneapi/tbb/flow_graph.h>

    namespace oneapi {
    namespace tbb {
    namespace flow {

        enum reset_flags {
            rf_reset_protocol = /*implementation-defined*/,
            rf_reset_bodies = /*implementation-defined*/,
            rf_clear_edges = /*implementation-defined*/
        };

    } // namespace flow
    } // namespace tbb
    } // namespace oneapi

Its enumerated values and their meanings are as follows:

- `rf_reset_protocol` - All buffers are emptied, internal state of nodes reinitialized. All calls to `reset()` perform these actions.

- `rf_reset_bodies` - When nodes with bodies are created, the body specified in the constructor is copied and preserved. When `rf_reset_bodies` is specified, the current body of the node is deleted and replaced with a copy of the body saved during construction.

  Caution

  If the body contains state which has an external component (such as a file descriptor), the node may not behave the same on re-execution of the graph after body replacement. In this case, the node should be re-created.

- `rf_clear_edges` - All edges are removed from the graph.
