RSeqHeader (OCSIP 3.0.0 RA Type)

All Superinterfaces:

Cloneable, Header, RSeqHeader, Serializable
```
public interface RSeqHeader
extends RSeqHeader
```
Extension to the RSeqHeader interface.
Provides access to the sequence number of this RSeqHeader as a long.
This extension interface is necessary because JAIN SIP 1.2 changed CSeqHeader to use long, but neglected to update RSeq and RAck headers.

Since:

OCSIP RA Type 2.2

- Method Detail
  - getSeq
```
long getSeq()
```
    Gets the sequence number of this RSeqHeader as a long.
    
    Returns:
    
    the long value of the Sequence number of the RSeqHeader.
  - setSeq
```
void setSeq(long rseq)
     throws InvalidArgumentException
```
    Sets the sequence number value of the RSeqHeader of the provisional response. The sequence number MUST be expressible as a 32-bit unsigned integer and MUST be less than 2**32.
    
    Parameters:
    
    rseq - the new Sequence number of this RSeqHeader.
    
    Throws:
    
    InvalidArgumentException - if supplied value is less than ONE or greater than 2**32-1.
