## Record Parser

The record parser allows you to easily parse protocols which are delimited by a sequence of bytes, or fixed size records.

It transforms a sequence of input buffer to a sequence of buffer structured as configured (either fixed size or separated records).

For example, if you have a simple ASCII text protocol delimited by '\n' and the input is the following:

    buffer1:HELLO\nHOW ARE Y
    buffer2:OU?\nI AM
    buffer3: DOING OK
    buffer4:\n

The record parser would produce

    buffer1:HELLO
    buffer2:HOW ARE YOU?
    buffer3:I AM DOING OK

Let’s see the associated code:

    var RecordParser = require("vertx-js/record_parser");
    var Buffer = require("vertx-js/buffer");
    var parser = RecordParser.newDelimited("\n", function (h) {
      console.log(h.toString());
    });

    parser.handle(Buffer.buffer("HELLO\nHOW ARE Y"));
    parser.handle(Buffer.buffer("OU?\nI AM"));
    parser.handle(Buffer.buffer("DOING OK"));
    parser.handle(Buffer.buffer("\n"));

You can also produce fixed sized chunks as follows:

    var RecordParser = require("vertx-js/record_parser");
    RecordParser.newFixed(4, function (h) {
      console.log(h.toString());
    });
