public class TokenBuffer
extends com.fasterxml.jackson.core.JsonGenerator
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.
Note that before version 2.0, this class was located in the "core" bundle, not data-binding; but since it was only used by data binding, was moved here to reduce size of core package

sense: we can not make good use of streaming because buffer must
hold all the data.
