Method Detail

setPollTimeout

public void setPollTimeout(long timeout)

Sets the timeout in milliseconds for polling operations.

Parameters:

timeout - the timeout in milliseconds for polling operations

setHost

public void setHost(java.lang.String host)

Sets this host to bind the publisher to.

Parameters:

host - the host

init

public void init()

connectToSender

public void connectToSender(java.lang.String id,
                   java.net.URI uri,
                   java.util.List<org.fabric3.spi.container.wire.InvocationChain> chains,

Parameters:

id - the connection id

uri - the target service URI

chains - the invocation chains

metadata - the ZeroMQ metadata to configure the underlying socket

loader - the classloader to load invocation parameters with

Throws:

BrokerException - if a connection error occurs

releaseSender

public void releaseSender(java.lang.String id,
                 java.net.URI uri)
                   throws BrokerException

Description copied from interface: ZeroMQWireBroker

Releases a previous connection to a sender.

Specified by:

releaseSender in interface ZeroMQWireBroker

Parameters:

id - the connection id

uri - the target service URI

Throws:

BrokerException - if a connection error occurs
