在libjson中确定JSONNode对象类型(Determine JSONNode object type in libjson)

 我们正在将Json库从JsonCpp切换到libJson。 JsonCpp具有很好的函数来确定json值的对象类型。 是否有任何方法在libjson中获取此信息？ 
 
 例如，使用JsonCpp我们有以下内容： 
 
Json::Value property = properties[propertyName.get_utf8()];

if (property.isInt()) 
{
    // Do Something
}
else if (property.isUInt())
{
    // Do Something
}
else if (property.isDouble())
{
    // Do Something
}
else if ( property.isString() )
{
    // Do Something
}
 
 有没有办法确定JSONNode是否有字符串，int或double。 我知道你可以获得JSONNode类型，但是你可以获得该节点中值的对象类型。 例如，如果我有以下内容： 
 
JSONNode root(JSON_NODE);
node.push_back(JSONNode("", "node"));
node.push_back(JSONNode("", 10));
node.push_back(JSONNode("", 21.5f));
node.push_back(JSONNode("", true));
 
 是否有可能确定root中的第一个节点包含一个字符串，第二个节点是int，第三个是float等吗？ 

we are switching Json libaries from JsonCpp to libJson. JsonCpp has nice functions to determine the object type of a json value. Is there any equvialent way of getting this information in libjson?
 
For example, using JsonCpp we have the following:
 
Json::Value property = properties[propertyName.get_utf8()];

if (property.isInt()) 
{
    // Do Something
}
else if (property.isUInt())
{
    // Do Something
}
else if (property.isDouble())
{
    // Do Something
}
else if ( property.isString() )
{
    // Do Something
}
 
Is there any way to determine if a JSONNode has a string, int or double. I know you can get the JSONNode type, but can you get the object type for the value within that node. For example, if I have the following:
 
JSONNode root(JSON_NODE);
node.push_back(JSONNode("", "node"));
node.push_back(JSONNode("", 10));
node.push_back(JSONNode("", 21.5f));
node.push_back(JSONNode("", true));
 
Is it possible to determine that the first node in root contains a string, the second an int, the third a float etc?
