Interface NonBlockingInputFeeder

All Known Subinterfaces:
ByteArrayFeeder, ByteBufferFeeder
All Known Implementing Classes:
NonBlockingByteBufferJsonParser, NonBlockingJsonParser
public interface NonBlockingInputFeeder
Interface used by non-blocking JsonParser implementations to feed input to parse. Feeder is used by entity that feeds content to parse; at any given point only one chunk of content can be processed so caller has to take care to only feed more content when existing content has been parsed (which occurs when parser's nextToken is called). Once application using non-blocking parser has no more data to feed it should call endOfInput() to indicate end of logical input (stream) to parse.

  • Method Summary

    Modifier and Type
    Method
    Description
    void
    endOfInput()
    Method that should be called after last chunk of data to parse has been fed (with feedInput in sub-class); can be called regardless of what needMoreInput() returns.
    boolean
    needMoreInput()
    Method called to check whether it is ok to feed more data: parser returns true if it has no more content to parse (and it is ok to feed more); otherwise false (and no data should yet be fed).

  • Method Details

    • needMoreInput

      boolean needMoreInput()
      Method called to check whether it is ok to feed more data: parser returns true if it has no more content to parse (and it is ok to feed more); otherwise false (and no data should yet be fed).
      Returns:
      True if more input is needed (and can be fed); false if there is still some input to decode

    • endOfInput

      void endOfInput()
      Method that should be called after last chunk of data to parse has been fed (with feedInput in sub-class); can be called regardless of what needMoreInput() returns. After calling this method, no more data can be fed; and parser assumes no more data will be available.
