Interface MulticastParamsBean

All Superinterfaces:

SettableBean

public interface MulticastParamsBean

extends SettableBean

Topics with certain quality of service allowments can receive a signifigant performance boost by using multicast to receive messages rather than using a connection oriented protocol like TCP. These parameters can be configured with the bean returned.

getMulticastAddress

String getMulticastAddress()

The IP address that this topic uses to transmit messages to multicast consumers.

Returns:

The multicastAddress value

setMulticastAddress

void setMulticastAddress(String address)
                         throws IllegalArgumentException

Sets the value of the MulticastAddress attribute.

Parameters:

address - The multicast address to use with this topic

Throws:

IllegalArgumentException - if the argument is not a well-formed IP address.

See Also:

MulticastParamsBean.getMulticastAddress()

getMulticastPort

int getMulticastPort()

The IP port that this topic uses to transmit messages to multicast consumers.

Returns:

The IP port that will be used for multicast transmissions

setMulticastPort

void setMulticastPort(int port)
                      throws IllegalArgumentException

Sets the value of the MulticastPort attribute.

Parameters:

port - The IP multicast port to be used with this topic

Throws:

IllegalArgumentException

See Also:

MulticastParamsBean.getMulticastPort()

getMulticastTimeToLive

int getMulticastTimeToLive()

The number of routers that a message traverses en route to a consumer. A value of 1 limits the message to one subnet (which prevents it from traversing any routers).

This value is independent of the JMSExpirationTime value.

Returns:

The multicastTTL value

setMulticastTimeToLive

void setMulticastTimeToLive(int timeToLive)
                            throws IllegalArgumentException

Sets the value of the MulticastTimeToLive attribute.

Parameters:

timeToLive - The multicast TTL value to be used with this topic

Throws:

IllegalArgumentException

See Also:

MulticastParamsBean.getMulticastTimeToLive()

getTemplateBean

TemplateBean getTemplateBean()

Finds the template bean for this destination.

Returns:

The template bean that will be used for this destination, or null if this threshold bean is from a template or a template could not be found for this destination
