RAckHeader

• java.lang.Object
  • ParameterLessHeader

Fields Summary
public static Class	clazz Class handle.
public static final String	NAME Sequence header.
protected Integer	responseNum response number - it is actually a value of RSeq header in the reliable provisional response
protected Integer	cseqNum CSeq number : value of CSeq header field
protected String	method method name

Constructors Summary
public RAckHeader() Constructor. super(RACK);
public RAckHeader(int responseNumber, int cseqNumber, String method) Constructor given the sequence number and method. param responseNumber is the response number to assign. param cseqNumber is the CSeq number to assign. param method is the method string. this(); responseNum = new Integer(responseNumber); cseqNum = new Integer(cseqNumber); method = method;

Methods Summary
public java.lang.Object	clone() Copies the current instance. return copy of current object RAckHeader retval = new RAckHeader(); if (this.responseNum != null) retval.responseNum = new Integer(this.responseNum.intValue()); if (this.cseqNum != null) retval.cseqNum = new Integer(this.cseqNum.intValue()); retval.method = this.method; return retval;
public java.lang.String	encodeBody() Return canonical header content. (encoded header except headerName:) return encoded string. return responseNum + Separators.SP + cseqNum + Separators.SP + method.toUpperCase();
public boolean	equals(java.lang.Object other) Compare two RAck headers for equality. Equality of RAck headers means that the class, method, response number and cseq number are same for both the headers param other Object to compare against. return true if the two RAck headers are equals, false otherwise. if (! other.getClass().equals(this.getClass())) { return false; } RAckHeader that = (RAckHeader) other; if (! this.responseNum.equals(that.responseNum)) { return false; } if (! this.cseqNum.equals(that.cseqNum)) { return false; } if (! equalsIgnoreCase(this.method, that.method)) { return false; } return true;
public java.lang.String	getMethod() Get the method. return String the method. return method.toUpperCase();
public int	getResponseNumber() Gets the response number of this RAckHeaderHeader. return response number of the RAckHeaderHeader if (this.responseNum == null) return 0; else return this.responseNum.intValue();
public int	getSequenceNumber() Gets the sequence number of this RAckHeaderHeader. return sequence number of the RAckHeaderHeader if (this.cseqNum == null) return 0; else return this.cseqNum.intValue();
public java.lang.Object	getValue() Gets the header value. return the header value return responseNum + Separators.SP + cseqNum + Separators.SP + method.toUpperCase();
public void	setHeaderValue(java.lang.String value) Sets the header value field. param value is the value field to set. throws IllegalArgumentException if the value is invalid. int newResponseNo; int newSeqNo; String newMethod; String strCseqMethod; value = value.trim(); // Check if the sequence number presents int delimIndex1 = value.indexOf(' "); if (delimIndex1 == -1) { throw new IllegalArgumentException("Invalid value"); } try { String strResponse = value.substring(0, delimIndex1).trim(); newResponseNo = Integer.parseInt(strResponse); setResponseNumber(newResponseNo); } catch (IllegalArgumentException iae) { throw iae; } strCseqMethod = value.substring(delimIndex1, value.length()).trim(); int delimIndex2 = strCseqMethod.indexOf(' "); if (delimIndex2 == -1) { throw new IllegalArgumentException("Invalid value"); } try { String strCseq = strCseqMethod.substring(0, delimIndex2).trim(); newSeqNo = Integer.parseInt(strCseq); setSequenceNumber(newSeqNo); } catch (IllegalArgumentException iae) { throw iae; } newMethod = strCseqMethod.substring(delimIndex2, strCseqMethod.length()).trim(); setMethod(newMethod);
public void	setMethod(java.lang.String newMethod) Set the method member param newMethod Method to be set if (newMethod == null) throw new NullPointerException("parameter is null"); method = newMethod;
public void	setResponseNumber(int responseNumber) Sets the response number of this RAckHeaderHeader. param responseNumber is the response number to be set if (responseNumber < 0) throw new IllegalArgumentException ("the sequence number parameter is < 0"); responseNum = new Integer(responseNumber);
public void	setSequenceNumber(int sequenceNumber) Sets the sequence number of this RAckHeaderHeader. The sequence number MUST be expressible as a 32-bit unsigned integer and MUST be less than 2**31. param sequenceNumber - the sequence number to set. throws InvalidArgumentException -- if the seq number is <= 0 if (sequenceNumber < 0) throw new IllegalArgumentException ("the sequence number parameter is < 0"); cseqNum = new Integer(sequenceNumber);
