Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method and Description
`protected void`	`begin(int character, JsonType type)`
`ObjectReader`	`beginArray()` Starts reading an array.
`ObjectReader`	`beginObject()` Starts reading a object.
`void`	`close()`
`int`	`column()`
`protected ValueType`	`consumeLiteral()` Reads the next literal value into _booleanValue, _doubleValue or _intValue and returns the type of the readed literal, possible values are : INTEGER, DOUBLE, BOOLEAN, NULL.
`protected String`	`consumeString(int token)`
`protected ValueType`	`consumeValue()`
`JsonType`	`enclosingType()`
`protected void`	`end(int character, JsonType type)`

  - beginArray
```
public ObjectReader beginArray()
```
    Description copied from interface: ObjectReader

    a reference to the reader.
  - beginObject
```
public ObjectReader beginObject()
```
    Description copied from interface: ObjectReader
    
    Starts reading a object. Objects contain name/value pairs. Call ObjectReader.endObject() when the objects contains no more properties.
    
    Specified by:

  - nextObjectMetadata
```
public ObjectReader nextObjectMetadata()
```
    Description copied from interface: ObjectReader
    
    Will read nexts object metadata. You can call this method as many times as you want, with the condition that you use only ObjectReader.metadata(String) method.

    Specified by:
    
    endArray in interface ObjectReader
    
    Returns:
    
    a reference to the reader.
  - endObject
```
public ObjectReader endObject()
```
    Description copied from interface: ObjectReader
    
    Ends the object. If you were not in an object or the object contains more data, an exception will be thrown.
    
    Specified by:

```
    Reads the next literal value into _booleanValue, _doubleValue or _intValue and returns the type of the readed literal, possible values are : INTEGER, DOUBLE, BOOLEAN, NULL. When calling this method the _cursor must be positioned on the first character of the value in the _buffer, you can ensure that by calling readNextToken(boolean).
