export class CCGuid {

this["#text"] = obj;
this["-deleteFlag"] = "N";
} else {
try {
this["-deleteFlag"] = obj["-deleteFlag"];

this["-deleteFlag"] = undefined;
}
try {
this["#text"] = obj["#text"];

export class CCGuid {
"-deleteFlag": string;
"#text": string;
constructor(obj: any) {
const deleteFlag = "-deleteFlag";
if (typeof obj === "string") {
this["#text"] = obj;
this[deleteFlag] = "N";
} else {
try {
this[deleteFlag] = obj[deleteFlag];
} catch {
this[deleteFlag] = undefined;
}
try {
this["#text"] = obj["#text"];
} catch {
this["#text"] = undefined;
}
}
}
}
I think this should do the trick with SQ, at least when it comes to that particular variable. You can do the same with "#text" of course.
After edit: sorry my first answer was broken, I was in a rush and didn't realize what I was really writing down.
Given my updated snippet, you can do the following:
this[deleteFlag']: This will work.
this['-deleteFlag']: This will of course work but Sonar Qube will complain because your use of duplicated string literals.
this.deleteFlag: This won't work because would be looking for a deleteFlag key on the object. Such key doesn't exist, it's '-deleteFlag'.
this['deleteFlag']: this is functionally the same as the line above. Would look for a 'deletFlag' key on the object, which doesn't exist.
Sorry for the confusion! Hope this helps now
