Method Detail

oneway

void oneway(Object command)
            throws IOException

A one way asynchronous send

Parameters:

command -

Throws:

IOException

asyncRequest

FutureResponse asyncRequest(Object command,
                            ResponseCallback responseCallback)
                            throws IOException

An asynchronous request response where the Receipt will be returned in the future. If responseCallback is not null, then it will be called when the response has been completed.

Parameters:

command -

responseCallback - TODO

Returns:

the FutureResponse

Throws:

IOException

request

Object request(Object command)
               throws IOException

A synchronous request response

Parameters:

command -

Returns:

the response

Throws:

IOException

request

Object request(Object command,
               int timeout)
               throws IOException

A synchronous request response

Parameters:

command -

timeout -

Returns:

the repsonse or null if timeout

Throws:

IOException

getTransportListener

TransportListener getTransportListener()

Returns the current transport listener

Returns:

setTransportListener

void setTransportListener(TransportListener commandListener)

Registers an inbound command listener

Parameters:

commandListener -

narrow

<T> T narrow(Class<T> target)

Parameters:

target -

Returns:

the target

getRemoteAddress

String getRemoteAddress()

Returns:

the remote address for this connection

isFaultTolerant

boolean isFaultTolerant()

Indicates if the transport can handle faults

Returns:

true if fault tolerant

isDisposed

boolean isDisposed()

Returns:

true if the transport is disposed

isConnected

boolean isConnected()

Returns:

true if the transport is connected

isReconnectSupported

boolean isReconnectSupported()

Returns:

true if reconnect is supported

isUpdateURIsSupported

boolean isUpdateURIsSupported()

Returns:

true if updating uris is supported

reconnect

void reconnect(URI uri)
               throws IOException

reconnect to another location

Parameters:

uri -

Throws:

IOException - on failure of if not supported

updateURIs

void updateURIs(boolean rebalance,
                URI[] uris)
                throws IOException

Provide a list of available alternative locations

Parameters:

rebalance -

uris -

Throws:

IOException

getReceiveCounter

int getReceiveCounter()

Returns a counter which gets incremented as data is read from the transport. It should only be used to determine if there is progress being made in reading the next command from the transport. The value may wrap into the negative numbers.

Returns:

a counter which gets incremented as data is read from the transport.
