public class TokenBuffer
extends com.fasterxml.jackson.core.JsonGenerator
```
Utility class used for efficient storage of JsonToken sequences, needed for temporary buffering. Space efficient for different sequence lengths (especially so for smaller ones; but not significantly less efficient for larger), highly efficient for linear iteration and appending. Implemented as segmented/chunked linked list of tokens; only modifications are via appends.

    Method used to create a JsonParser that can read contents stored in this buffer. Will use default _objectCodec for object conversions.
    Note: instances are not synchronized, that is, they are not thread-safe if there are concurrent appends to the underlying buffer.

    Parameters:
    
    codec - Object codec to use for stream-based object conversion through parser/generator interfaces. If null, such methods cannot be used.

```
    Helper method that will write all contents of this buffer using given JsonGenerator.
    Note: this method would be enough to implement JsonSerializer for TokenBuffer type; but we cannot have upwards references (from core to mapper package); and as such we also cannot take second argument.

    java.io.IOException
