## 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 an 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:

    import io.vertx.groovy.core.parsetools.RecordParser
    import io.vertx.groovy.core.buffer.Buffer
    def parser = RecordParser.newDelimited("\n", { h ->
      println(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:

    import io.vertx.groovy.core.parsetools.RecordParser
    RecordParser.newFixed(4, { h ->
      println(h.toString())
    })
