class RecordParser extends ReadStream[Buffer] with Handler[Buffer]
A helper class which allows you to easily parse protocols which are delimited by a sequence of bytes, or fixed size records.
Instances of this class take as input io.vertx.scala.core.buffer.Buffer instances containing raw bytes, and output records.
For example, if I had a simple ASCII text protocol delimited by '\n' and the input was the following:
buffer1:HELLO\nHOW ARE Y buffer2:OU?\nI AM buffer3: DOING OK buffer4:\nThen the output would be:
buffer1:HELLO buffer2:HOW ARE YOU? buffer3:I AM DOING OKInstances of this class can be changed between delimited mode and fixed size record mode on the fly as individual records are read, this allows you to parse protocols where, for example, the first 5 records might all be fixed size (of potentially different sizes), followed by some delimited records, followed by more fixed size records.
Instances of this class can't currently be used for protocols where the text is encoded with something other than a 1-1 byte-char mapping.
Please see the documentation for more information.
