Method Summary

Modifier and Type	Method and Description
ReadOptions	getReadOptions()
ReferenceTracker	getReferences()
<T> T	reentrantConvertParsedMapsToJava(JsonObject root, Class<T> hint) This method converts a rootObj Map, (which contains nested Maps and so forth representing a Java Object graph), to a Java object instance.
void	traverseFields(Deque<JsonObject> stack, JsonObject jsonObj) Walk the Java object fields and copy them from the JSON object to the Java object, performing any necessary conversions on primitives, or deep traversals for field assignments to other objects, arrays, Collections, or Maps.

reentrantConvertParsedMapsToJava

<T> T reentrantConvertParsedMapsToJava(JsonObject root,
                                       Class<T> hint)

This method converts a rootObj Map, (which contains nested Maps and so forth representing a Java Object graph), to a Java object instance. The rootObj map came from using the JsonReader to parse a JSON graph (using the API that puts the graph into Maps, not the typed representation).

Parameters:

root - JsonObject instance that was the rootObj object from the

hint - When you know the type you will be returning. Can be null (effectively Map.class) JSON input that was parsed in an earlier call to JsonReader.

Returns:

a typed Java instance that was serialized into JSON.

traverseFields

void traverseFields(Deque<JsonObject> stack,
                    JsonObject jsonObj)

Walk the Java object fields and copy them from the JSON object to the Java object, performing any necessary conversions on primitives, or deep traversals for field assignments to other objects, arrays, Collections, or Maps.

Parameters:

stack - Stack (Deque) used for graph traversal.

jsonObj - a Map-of-Map representation of the current object being examined (containing all fields).
