Interface: IStateReconciler<TState>#

Defined in: retree-query/bin/types.d.ts:86

Reconciles an incoming query value against the current node state.

Type Parameters#

Type Parameter
`TState`

Methods#

reconcile()#

reconcile(
   current, 
   next, 
   rawCurrent?): TState;

Defined in: retree-query/bin/types.d.ts:109

Reconcile next into current.

Parameters#

Parameter	Type	Description
`current`	`TState` \| `undefined`	Current query state, if any. Write surface.
`next`	`TState`	Newly emitted query state (raw server data).
`rawCurrent?`	`TState`	Raw view of `current` for fast reads; `undefined` when `current` is `undefined` or not object-valued.

Returns#

TState

The state object that should be assigned to the query node.

Remarks#

Reconciliation is read-dominated: it compares every field and writes only the diffs. Read from rawCurrent, write to current. rawCurrent is the raw object behind current (Retree.raw) — native-speed, proxy-free reads. Writes must go through current so changed rows emit nodeChanged and item identity stays stable for useNode rows; writes to rawCurrent skip emission entirely.

next may be shared with other queries and the source's cache, so never write its objects into current directly. reconcileArray copies what it writes, and a returned replacement value is copied except for rows it reuses from current.
