# canAddNode(_:)

Returns whether the given node can be added to the graph.

## Declaration

```swift
func canAddNode(_ node: ComputeNodeGraph.Node) -> Bool
```

## Parameters

- `node`: The node to test.

## Return Value

Return Value true if calling addNode(_:) with this node would succeed.

## Discussion

Discussion This is the non-throwing preflight check for addNode(_:). Use it to validate a node — for example, to gate UI affordances — without modifying the graph.
