    Description copied from interface: Decoder
    Decodes the current state into an arbitrary object.
    The following should be decoded by this method:
    - Object types will be decoded into a Map
    - Array types will be decoded into a List
    - JSON primitive types into the equivalent Java wrapper type
    Specified by:
    
    decodeArbitrary in interface Decoder
    
    Returns:
    
    The decoded object

public Decoder decodeBuffer()
                     throws java.io.IOException
```
    Description copied from interface: Decoder
    
    Buffer the whole subtree of this value and return it as a new Decoder. The returned Decoder can be used independently to this Decoder. This means actual parsing of the subtree can be delayed.
    The returned Decoder should behave identically to this Decoder. This means that for example decoder.decodeDouble() should be equivalent to decoder.decodeBuffer().decodeDouble().
    
    Specified by:
    
    decodeBuffer in interface Decoder
    
    Returns:
    
    An independent decoder that visits this subtree.
    
    Throws:
    
    java.io.IOException - If an unrecoverable error occurs
  - createDeserializationException
```
public java.io.IOException createDeserializationException(java.lang.String message,

```
    Description copied from interface: Decoder
    
    Creates an exception for the given message.
    
    Specified by:
    
    createDeserializationException in interface Decoder
    
    Parameters:
    
    message - The message, never null
    
    invalidValue - The invalid value. Can be null.
    
    Returns:
    
    The exception, never null
