RecordParser (Vert.x Stack - Docs 4.2.7 API)

java.lang.Object
- io.vertx.reactivex.core.parsetools.RecordParser

All Implemented Interfaces:

Handler<Buffer>, ReadStream<Buffer>, StreamBase
```
public class RecordParser
extends Object
implements ReadStream<Buffer>, 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 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:\n
 
```
Then the output would be:
```
 buffer1:HELLO
 buffer2:HOW ARE YOU?
 buffer3:I AM DOING OK
 
```
Instances 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.
NOTE: This class has been automatically generated from the original non RX-ified interface using Vert.x codegen.
