TreeSplicing class abstract final

Subtree replacement operations on green trees.

Only replaceAt is provided. rumil-scala's TreeSplicing also exposes replaceChildRange, findNode, and pathToOffset, but its IncrementalParser uses none of them — it splices exclusively through replaceAt (token-level and block-level paths alike). pathToOffset is in any case redundant here: RedTree.nodeAt(offset).pathFromRoot already gives a splice path from an offset. So those three are deliberately not ported — building them ahead of a consumer would be speculative surface area. A range-replace can be added additively if a real consumer needs one.

Static Methods

replaceAt<Tok, Syn>(GreenNode<Tok, Syn> root, List<int> path, GreenNode<Tok, Syn> replacement) → GreenNode<Tok, Syn>?

Replace the node at path in root with replacement, returning a new root. Returns null if path does not resolve — an index out of range, or descending into a leaf (GreenToken / GreenMissing) that has no children.
