rune-langium / core/src / RuneStoreHydrator

Class: RuneStoreHydrator

Defined in: packages/core/src/services/rune-store-hydrator.ts:32

Hydrator variant for the Rune store substrate.

Differences from DefaultHydrator:

• CST nodes are dropped entirely — the store has no use for parse-tree data. ($cstNode, $containerIndex, and $containerProperty are deleted from the output so the runtime object matches the Dehydrated<T> type, which excludes all Langium runtime fields.)
• $cstText (a custom field stamped by preserveCstText BEFORE dehydration) is preserved — the visual editor's expression cells read it after the round-trip, and DefaultHydrator would otherwise drop it as a $-field.
• References are stored as { $refText: string } only — the editable Dehydrated<T> wire format.
• Re-hydration rebuilds a proper Reference via this.linker.buildReference, passing undefined for the CST node (consistent with the drop above).
• $namespace is stamped from the enclosing RosettaModel before $container is stripped.

Methods

createDehyrationContext()

protected createDehyrationContext(node): DehydrateContext;

Defined in: packages/core/src/services/rune-store-hydrator.ts:44

CST nodes never survive dehydration here (see class doc), so skip the base class's full CST-tree walk when building the context — on large corpora that walk dominates dehydration cost for zero benefit.

node	AstNode

Returns

DehydrateContext

hydrate()

hydrate<T>(result): ParseResult<T>;

Defined in: node_modules/.pnpm/[email protected]/node_modules/langium/lib/serializer/hydrator.d.ts:55

Converts a plain object to a parse result. The included AST node can then be used in the main thread. Calling this method on objects that have not been dehydrated first will result in undefined behavior.
