Constructor Detail

MsgHeader

public MsgHeader(MsgHeader pHdr)

Ctor.

Parameters:

pHdr -

MsgHeader

public MsgHeader(int pVersion,
                 int pFunctionID,
                 java.lang.String pLangTag,
                 boolean pOverflow,
                 boolean pFresh,
                 boolean pMCast,
                 int pXID)

Ctor.

Parameters:

pVersion -

pFunctionID -

pMCast -

pXID -

Method Detail

parse

public static MsgHeader parse(SLPInputStream pInStr)
                       throws ServiceLocationException,
                              java.io.IOException

parse

Parameters:

pInStr -

Returns:

MsgHeader

Throws:

ServiceLocationException

java.io.IOException

getVersion

public int getVersion()

getVersion

Returns:

int

getFunctionID

public int getFunctionID()

getFunctionID

Returns:

int

getLangTag

public java.lang.String getLangTag()

getLangTag

Returns:

int

overflows

public boolean overflows()

overflows

Returns:

boolean

fresh

public boolean fresh()

fresh

Returns:

boolean

multicast

public boolean multicast()

multicast

Returns:

boolean

getXID

public int getXID()

Returns:

the XID which is parsed from the message. serialize() doesn't use this value, that serializes a new XID into the stream at every call (unless pKeepXID is set).

setXID

public void setXID(int pXID)

The response have to contain the same XID of the request. So this setter can be useful.

Parameters:

pXID -

getSize

public int getSize()

getSize

Returns:

int

serialize

public byte[] serialize(int pBodyLength,
                        boolean pOverflow,
                        boolean pSetMultiCastFlag,
                        boolean pKeepXID)

serialize

Parameters:

pBodyLength -

pOverflow -

pSetMultiCastFlag -

pKeepXID -

Returns:

byte[]
