示例1: switchMap
switchMap((action: ExecuteCell) => {
const { id } = action.payload;
const state = state$.value;
const contentRef = action.payload.contentRef;
const model = selectors.model(state, { contentRef });
// If it's not a notebook, we shouldn't be here
if (!model || model.type !== "notebook") {
return empty();
}
const cell = selectors.notebook.cellById(model, {
id
});
if (!cell) {
return empty();
}
// We only execute code cells
