RAckHeader (OCSIP 3.1 RA Type)

All Superinterfaces:

Cloneable, javax.sip.header.Header, javax.sip.header.RAckHeader, Serializable
```
public interface RAckHeader
extends javax.sip.header.RAckHeader
```
Extension to the RAckHeader interface.
Provides access to CSeq and RSeq sequence numbers as longs.
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
  - getCSeq
```
long getCSeq()
```
    Gets the CSeq sequence number of this RAckHeader as a long.
    
    Returns:
    
    the long value of the CSeq number of the RAckHeader.
  - setCSeq
```
void setCSeq(long cseq)
      throws javax.sip.InvalidArgumentException
```
    Sets the sequence number value of the CSeqHeader of the provisional response being acknowledged. The sequence number MUST be expressible as a 32-bit unsigned integer and MUST be less than 2**32.
    
    Parameters:
    
    cseq - the new CSeq number of this RAckHeader.
    
    Throws:
    
    javax.sip.InvalidArgumentException - if supplied value is less than ZERO or greater than 2**32-1.
  - getRSeq
```
long getRSeq()
```
    Gets the RSeq sequence number of this RAckHeader as a long.
    
    Returns:
    
    the long value of the RSeq number of the RAckHeader.
  - setRSeq
```
void setRSeq(long rseq)
      throws javax.sip.InvalidArgumentException
```
    Sets the sequence number value of the RSeqHeader of the provisional response being acknowledged. The sequence number MUST be expressible as a 32-bit unsigned integer and MUST be less than 2**32.
    
    Parameters:
    
    rseq - the new RSeq number of this RAckHeader.
    
    Throws:
    
    javax.sip.InvalidArgumentException - if supplied value is less than ONE or greater than 2**32-1.
