removeNode

removeNode(node: undefined | TreeNode): void
Remove the given node and all of its descendants from the tree's internal id-to-node index. Safe to call on already-detached subtrees.

Callers that mutate the tree structure directly via CompositeTreeNode.removeChild should invoke this (or pass the tree to removeChild) to keep getNode and validateNode from returning orphaned nodes.
Parameters

Parameters
- uri: URI
- parent: CompositeTreeNode
Returns string
Inherited from FileTree.toNodeId
- Defined in packages/filesystem/src/browser/file-tree/file-tree.ts:96
