getTreeElement()function

getTreeElement(map: ReadonlyMap<string, TreeElement>, ref: string): TreeElement | undefined

Param	Type
`map`	`ReadonlyMap<string, TreeElement>`	The flattened tree lookup map (from `useTreeMap()`). required
`ref`	`string`	The reference string — a flat key, canonical path, or token written in its display form. required

Return
`TreeElement \| undefined`	The resolved element, or `undefined` on a miss.

Resolve a reference string to its tree element — by exact key first, then by a normalised key with the prose display decorations stripped.

Exact lookup handles flat keys ("BooleanSchema", "Store.get") and canonical paths ("/schema/BooleanSchema").
On a miss, the reference is normalised so a token written in its prose display form still resolves: generics ("Schema<T>" → "Schema"), call parens ("formatDate()" / "Store.get()" → bare name), component angle brackets ("<Section>" → "Section"), and the module package prefix ("shelving/schema" → the "/schema" canonical path). This is what lets a bare backtick reference in markup auto-link.
A qualified "Owner.member" whose member has no page of its own falls back to the owner's (class/interface) page — so "StringSchema.validate()" still links even when validate isn't a standalone token.
A compound reference ("Schema<T> | null", "Omit<X, 'k'>") only retries on the leading identifier when the whole string is Identifier<…>; otherwise it stays a miss and the caller falls back to plain text.

Examples

getTreeElement(useTreeMap(), "formatDate()") // the `formatDate` element
