    • _currInputRowStart

      protected int _currInputRowStart

    • _tokenInputTotal

      protected long _tokenInputTotal
      Total number of bytes/characters read before start of current token. For big (gigabyte-sized) sizes are possible, needs to be long, unlike pointers and sizes related to in-memory buffers.

      Input row on which current token starts, 1-based

    • _tokenInputCol

      protected com.fasterxml.jackson.core.util.ByteArrayBuilder _byteArrayBuilder
      ByteArrayBuilder is needed if 'getBinaryValue' is called. If so, we better reuse it for remainder of content.

    • _binaryValue

      protected byte[] _binaryValue
      We will hold on to decoded binary data, for duration of current event, so that multiple calls to getBinaryValue(Base64Variant) will not need to decode data more than once.

    • _tagValues

    • _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
      Current buffer from which data is read; generally data is read into buffer from input source, but in some cases pre-loaded buffer is handed to the parser.

    • _bufferRecyclable

      protected boolean _bufferRecyclable
      Flag that indicates whether the input buffer is recycable (and needs to be returned to recycler once we are done) or not.

      Note that in particular this method DOES NOT reset state that nextToken() would do, but will change current token type to allow access.
