I have the following code:
void MyClass::myMethod(Json::Value& jsonValue_ref)
{
for (int i = 0; i <= m_stringList.size(); i++)
{
if (m_boolMarkerList[i])
{
jsonValue_ref.append(stringList[i]);
}
}
}
void MyClass::myOuterMethod()
{
Json::Value jsonRoot;
Json::Value jsonValue;
myMethod(jsonValue);
jsonRoot["somevalue"] = jsonValue;
Json::StyledWriter writer;
std::string out_string = writer.write(jsonRoot);
}
If all markers in m_boolMarkerList
are false, the out_string
is { "somevalue" : null }
, but I want it to be an empty array: { "somevalue" : [ ] }
Does anybody know how to achieve this?
Thank you very much!
Here are two ways you can do it:
jsonRootValue["emptyArray"] = Json::Value(Json::arrayValue);
// or
jsonRootValue["emptyArray"] = Json::arrayValue;
