message. This
message is sent from a server to a client via TCP if a channel that has been
connected before is now disconnected by the server. For example, this might
happen if a formerly active channel is removed from the server.ChannelAccessCommand.CA_PROTO_SERVER_DISCONN

- the channel CID. This is the identifier used by the client to
identify the channel.public int getChannelCID()

byteSink
- byte sink that is used for writing the serialized data.version
- protocol version to stay compatible with. This is the protocol
version of the peer the message is sent to.maxPayloadSize
- maximum size of the payload.charset
- encoding to use for serializing the string data (e.g. channel
names, error strings, string data-values).public boolean equals(java.lang.Object obj)
ChannelAccessMessage
Tells whether the specified object represents the same message.
Two messages are considered equal if they are of the same type and have the same headers and payload. For comparing the types, the actual Java type and not just the Channel Access command is compared.
equals
in class ChannelAccessMessage
obj
- reference object with which this object is compared.true
if obj
is a message that is of the
same type and has the same headers and payload as this message.
false
if obj
is null
or of
a different type than this message or differs in the headers or
payload.public int hashCode()
ChannelAccessMessage
Returns a hash code value for this message. This method is supported for the benefit of hash tables. The hash code is calculated as a combination of the hash codes of this messages headers (including the Channel Access command) and its payload (if present).
If two messages are equal (as indicated by the return value of
ChannelAccessMessage.equals(Object)
), they also have the same hash code. However, the
fact that two messages have the same hash code does not imply that they
are equal.
