memberVariables method

AFMemberVariableTemplates? memberVariables(AFCommandContext context, AFCommandArgumentsParsed args, String mainType, { bool isAugment = false, bool? isIntIdOverride, })

Utility for parsing the --member-variables and --resolve-variables flags, if present.

Implementation

AFMemberVariableTemplates? memberVariables(AFCommandContext context, AFCommandArgumentsParsed args, String mainType, {
  bool isAugment = false,
  bool? isIntIdOverride,

  final memberVars = _parseSemicolonDeclarations(context, memberVarsSource);

  // currently, allowing them to have no member variables adds a lot of complexity, because you then have to worry about
  // adding in {} in a bunch of places.   So, for now, just force them to always have at least one variable.
  if(memberVars.isEmpty) {
    context.output.writeTwoColumns(col1: "info ", col2: "Adding tempPlaceholder member variable due to issues with 'generate augment' in scenarios with no member variables.");
    memberVars[AFMemberVariableTemplates.tempPlaceholderVarName] = "int";
  }


  // if they specified serial, then make sure they specified an ID.
  var isIntId = false;
  if(!isRoot && !isQuery && !args.accessNamedFlag(AFGenerateStateSubcommand.argNotSerial)) {
    var idType = memberVars[AFDocumentIDGenerator.columnId];

      writeConvertingIntIdMessage(context);
    }
