invalidate method

void invalidate()

The next query rebuilds the cache. The document's changes stream delivers only after the task that made a change, so whatever reads the cache in the task of an edit calls this first: it must never read an input the document no longer has. The Room tool calls it at its click and again right after its execute; the Separator tool at its second click, before the trim, and again right after its execute; the separator grips at release, before they trim, since they never execute (the select tool executes the command they return).

Implementation

void invalidate() {
  _stale = true;
  _generation++;
}
