boolProperty method

BoolProperty boolProperty (String name)

Returns an BoolProperty with name on this node.

If an BoolProperty with name already exists and is not deleted, this method returns it.

Otherwise, it creates a new property initialized to false.

Throws InspectStateError if a non-deleted property with name already exists but it is not a BoolProperty.


BoolProperty boolProperty(String name) {
  if (_writer == null) {
    return BoolProperty._deleted();
  if (_properties.containsKey(name)) {
    if (_properties[name] is! BoolProperty) {
      throw InspectStateError(
          "Can't create BoolProperty named $name; a different type exists.");
    return _properties[name];
  return _properties[name] = BoolProperty._(name, this, _writer);
