copyWith method

XmlDoctype copyWith({ String? element, bool? isSystem, bool? isPublic, String? externalDtdName, String? externalDtdUri, List<XmlNode>? externalDtd, List<XmlNode>? internalDtd, bool copyNull = false, })

Copies this DocType declaration with the provided values.

name must be > 0 in length if not null.

Either isSystem or isPublic may be true, not both.

If copyNull is true, externalDtdName, externalDtdUri, externalDtd, and internalDtd will be copied with a value of null if they're not provided with another value, otherwise they will default to this element's values.

Implementation

XmlDoctype copyWith({
  String? element,
  bool? isSystem,
  bool? isPublic,
  String? externalDtdName,
  String? externalDtdUri,
  List<XmlNode>? externalDtd,
  List<XmlNode>? internalDtd,
  bool copyNull = false,
}) {
  assert(element == null || element.isNotEmpty);
  assert(isPublic == null || isSystem == null || !(isPublic && isSystem));

  if (!copyNull) {
    externalDtdName ??= this.externalDtdName;
    externalDtdUri ??= this.externalDtdUri;
    externalDtd ??= this.externalDtd;
    internalDtd ??= this.internalDtd;
  }

  isSystem ??= isPublic == true ? false : this.isSystem;
  isPublic ??= isSystem == true ? false : this.isPublic;

  return XmlDoctype(
    element: element ?? this.element,
    isSystem: isSystem,
    isPublic: isPublic,
    externalDtdName: externalDtdName,
    externalDtdUri: externalDtdUri,
    externalDtd: externalDtd,
    internalDtd: internalDtd,
  );
}
