Method Detail

prepare

protected void prepare(Map stormConfig)

Overrides:

prepare in class TupleToMessage

determineExchangeName

protected String determineExchangeName(backtype.storm.tuple.Tuple input)

Description copied from class: TupleToMessage

Determine the exchange where the message is published to. This can be derived based on the incoming tuple or a fixed value.

Specified by:

determineExchangeName in class TupleToMessage

Parameters:

input - the incoming tuple

Returns:

the exchange where the message is published to.

determineRoutingKey

protected String determineRoutingKey(backtype.storm.tuple.Tuple input)

Description copied from class: TupleToMessage

Determine the routing key used for this message. This can be derived based on the incoming tuple or a fixed value. Default implementation provides no routing key.

Overrides:

determineRoutingKey in class TupleToMessage

Parameters:

input - the incoming tuple

Returns:

the routing key for this message

specifyContentType

protected String specifyContentType(backtype.storm.tuple.Tuple input)

Description copied from class: TupleToMessage

Specify message body content type. Default implementation skips the provision of this detail.

Overrides:

specifyContentType in class TupleToMessage

Parameters:

input - the incoming tuple

Returns:

content type

specifyContentEncoding

protected String specifyContentEncoding(backtype.storm.tuple.Tuple input)

Description copied from class: TupleToMessage

Specify message body content encoding. Default implementation skips the provision of this detail.

Overrides:

specifyContentEncoding in class TupleToMessage

Parameters:

input - the incoming tuple

Returns:

content encoding

specifyMessagePersistence

protected boolean specifyMessagePersistence(backtype.storm.tuple.Tuple input)

Description copied from class: TupleToMessage

Specify whether each individual message should make use of message persistence when it's on a rabbitmq queue. This does imply queue durability or high availability or just avoidance of message loss. To accomplish that please read rabbitmq docs on High Availability, Publisher Confirms and Queue Durability in addition to having this return true. By default, message persistence returns false.

Overrides:

specifyMessagePersistence in class TupleToMessage

Parameters:

input - the incoming tuple

Returns:

whether the message should be persistent to disk or not. Defaults to not.
