TokenBuffer (jackson-databind 2.15.0)

java.lang.Object
- com.fasterxml.jackson.core.JsonGenerator
- - com.fasterxml.jackson.databind.util.TokenBuffer

All Implemented Interfaces:

Versioned, Closeable, Flushable, AutoCloseable
```
public class TokenBuffer
extends 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.

    True if this buffer instance has no tokens

  - append
```
public TokenBuffer append(TokenBuffer other)
                   throws IOException
```
    Helper method that will append contents of given buffer into this buffer. Not particularly optimized; can be made faster if there is need.
    
    Returns:
    
    This buffer
    
    Throws:
    
    IOException
  - serialize
```
public void serialize(JsonGenerator gen)
               throws IOException
```
    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.
    
    Throws:
    
    IOException
  - deserialize
