Method Detail

getParameter

public Buffer getParameter(Buffer name)
                    throws SipParseException

Description copied from interface: Parameters

Get the value of the named parameter. If the named parameter is a so-called flag parameter, then the value returned will be an empty Buffer, which can be checked with Buffer.isEmpty() or Buffer.capacity(), which will return zero. As with any empty Buffer, if you do Buffer.toString() you will be getting an empty String back, which would be yet another way to check for a flag parameter.

Specified by:

getParameter in interface Parameters

Parameters:

name - the name of the parameter we are looking for.

Returns:

the value of the named parameter or null if there is no such parameter. If the named parameter is a flag parameter, then an empty buffer will be returned.

Throws:

SipParseException - in case anything goes wrong while extracting the parameter.

getParameter

public Buffer getParameter(String name)
                    throws SipParseException

Description copied from interface: Parameters

Same as Parameters.getParameter(Buffer).

Specified by:

getParameter in interface Parameters

Returns:

Throws:

SipParseException - in case anything goes wrong while extracting the parameter.

setParameter

public Buffer setParameter(Buffer name,
                  Buffer value)
                    throws SipParseException,
                           IllegalArgumentException

Description copied from interface: Parameters

Sets the value of the specified parameter. If there already is a parameter with the same name its value will be overridden. A value of null or a zero length buffer means that this parameter is a flag parameter

Specified by:

setParameter in interface Parameters

Parameters:

name - the name of the parameter

value - the value of the parameter or null if you just want to set a flag parameter

Returns:

the previous value or null if there were none associated with this parameter name

Throws:

SipParseException - in case anything goes wrong when setting the parameter.

IllegalArgumentException - in case the name is null or empty.

getValue

public Buffer getValue()

Will only return the parameters. Sub-classes will have to build up the rest of the buffer Get the value of the buffer

Specified by:

getValue in interface SipHeader

Overrides:

getValue in class SipHeaderImpl

Returns:

transferValue

protected void transferValue(Buffer dst)

Description copied from class: SipHeaderImpl

Transfer the bytes of the value into the destination. Sub-classes should override this method.

Overrides:

transferValue in class SipHeaderImpl
