Method Detail

getAddress

Member getAddress()
Get the address that this message originated from. Almost always Channel.getLocalMember(boolean)
This would be set to a different address if the message was being relayed from a host other than the one that originally sent it.

Returns:
the source or reply-to address of this message

setAddress

void setAddress(Member member)
Sets the source or reply-to address of this message

Parameters:
member - Member

getTimestamp

long getTimestamp()
Timestamp of when the message was created.

Returns:
long timestamp in milliseconds

setTimestamp

void setTimestamp(long timestamp)
Sets the timestamp of this message

Parameters:
timestamp - The timestamp

getUniqueId

byte[] getUniqueId()
Each message must have a globally unique Id. interceptors heavily depend on this id for message processing

Returns:
byte

setMessage

void setMessage(XByteBuffer buf)
The byte buffer that contains the actual message payload

Parameters:
buf - XByteBuffer

getMessage

XByteBuffer getMessage()
returns the byte buffer that contains the actual message payload

Returns:
XByteBuffer

getOptions

int getOptions()
The message options is a 32 bit flag set that triggers interceptors and message behavior.

Returns:
int - the option bits set for this message
See Also:
Channel.send(Member[], Serializable, int), ChannelInterceptor.getOptionFlag()

setOptions

void setOptions(int options)
sets the option bits for this message

Parameters:
options - int
See Also:
getOptions()

clone

java.lang.Object clone()
Shallow clone, what gets cloned depends on the implementation

Returns:
ChannelMessage

deepclone

java.lang.Object deepclone()
Deep clone, all fields MUST get cloned

Returns:
ChannelMessage
