All Implemented Interfaces:

Message

Direct Known Subclasses:

ConcentratorMessage, StandaloneMessage
```
public abstract class RfidMessage
extends AbstractMRMessage
```
Contains the data payload of a serial packet.
The transmission protocol can come in one of several forms:
- If the interlocked parameter is false (default), the packet is just sent. If the response length is not zero, a reply of that length is expected.
- If the interlocked parameter is true, the transmission will require a CRC interlock, which will be automatically added. (Design note: this is done to make sure that the messages remain atomic)
Since:

2.11.4

Constructors
Modifier	Constructor	Description
`protected`	`RfidMessage()`	Suppress the default ctor, as the length must always be specified
	`RfidMessage(byte[] a, int l)`	This ctor interprets the byte array as a sequence of characters to send.
	`RfidMessage(int l)`
	`RfidMessage(java.lang.String m, int l)`	This ctor interprets the String as the exact sequence to send, byte-for-byte.
