Field Details

_objectCodec

protected com.fasterxml.jackson.core.ObjectCodec _objectCodec

Codec used for data binding when (if) requested.

_inputStream

protected InputStream _inputStream

Input stream that can be used for reading more content, if one in use. May be null, if input comes just as a full buffer, or if the stream has been closed.

_inputBuffer

protected byte[] _inputBuffer

If it is not, it also means that parser can NOT modify underlying buffer.

_typeAsInt

protected int _typeAsInt

Type byte of the current token (as in)

_tokenIncomplete

protected boolean _tokenIncomplete

Flag that indicates that the current token has not yet been fully processed, and needs to be finished for some access (or skipped to obtain the next token)
