JsonObject (json-io 4.19.0 API)

java.lang.Object
- java.util.AbstractMap<K,V>
- - java.util.HashMap<K,V>
  - - java.util.LinkedHashMap<Object,Object>
    - - com.cedarsoftware.util.io.JsonObject

All Implemented Interfaces:

Serializable, Cloneable, Map<Object,Object>
```
public class JsonObject
extends LinkedHashMap<Object,Object>
```
This class holds a JSON object in a LinkedHashMap. LinkedHashMap used to keep fields in same order as they are when reflecting them in Java. Instances of this class hold a Map-of-Map representation of a Java object, read from the JSON input stream.

  - hasId
```
public boolean hasId()
```
    A JsonObject starts off with an id of -1. Also, an id of 0 is not considered a valid id. It must be 1 or greater. JsonWriter utilizes this fact.
  - isFinished
```
public boolean isFinished()
```
  - setFinishedTarget
```
public Object setFinishedTarget(Object o,
                                boolean isFinished)

```
public boolean isLogicalPrimitive()
```
  - getPrimitiveValue
```
public Object getPrimitiveValue()
```
  - isReference
```
public boolean isReference()
```
    Returns:
    
    boolean true if this object references another object, false otherwise.
