interruptHandler property

FutureOr<void> Function(NotebookDocument)? get interruptHandler

Optional interrupt handler.

By default cell execution is canceled via {@link NotebookCellExecution.token tokens}. Cancellation tokens require that a controller can keep track of its execution so that it can cancel a specific execution at a later point. Not all scenarios allow for that, eg. REPL-style controllers often work by interrupting whatever is currently running. For those cases the interrupt handler exists - it can be thought of as the equivalent of SIGINT or Control+C in terminals.

Note that supporting {@link NotebookCellExecution.token cancellation tokens} is preferred and that interrupt handlers should only be used when tokens cannot be supported.

Implementation

_i4.FutureOr<void> Function(_i3.NotebookDocument)? get interruptHandler =>
    (_i3.NotebookDocument p0) => _i5.callMethod(
          _i5.getProperty(
            this,
            'interruptHandler',
          ),
          r'call',
          [
            this,
            p0,
          ],
        );

set interruptHandler (FutureOr<void> value(NotebookDocument)?)

Implementation

set interruptHandler(
    _i4.FutureOr<void> Function(_i3.NotebookDocument)? value) {
  _i5.setProperty(
    this,
    'interruptHandler',
    value == null
        ? _i6.undefined
        : _i5.allowInterop((p0) => _i6.Promise.futureOr(() => value(p0))),
  );
