== 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, groovy]
----
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:

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