== 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:

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

The record parser would produce
[source]
----
buffer1:HELLO
buffer2:HOW ARE YOU?
buffer3:I AM DOING OK
----

Let's see the associated code:

[source, js]
----
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:

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