Detailed Description
JParserValFact is the JVal JSON parser factory class.
An instance of this class is connected to an instance of the JParser. The JParser communicates with the JVal factory when parsing JSON, and the JVal factory creates JVal objects.
Method getFirstVal returns the first value in the syntax tree.
The class automatically manages the nodes allocated. The allocated nodes are automatically de-allocated when the destructor runs. You can manage the values by calling JParserValFact::manageFirstVal or by calling JVal::manageJ on any of the children.

Member Data Documentation
◆ maxNodes
| U32 JParserValFact::maxNodes |
Node-count threshold, initially U32 maximum.
Allocation is refused when the incremented count reaches this value; it is an exclusive limit.
◆ status
| JParserValFactStat JParserValFact::status |
Factory status, initially OK; parse failures may set it.
Terminating or detaching the root does not clear this field.
