attachToGroup method

void attachToGroup(
  1. String groupName
)

Attaches this endpoint to an API group.

An endpoint may only belong to one group. Re-attaching to the same group is allowed so composition remains rerunnable.

Implementation

void attachToGroup(String groupName) {
  final existing = _groupName;
  if (existing != null && existing != groupName) {
    throw StateError(
      'Endpoint "$name" is already attached to API group "$existing".',
    );
  }
  _groupName = groupName;
}
