public class ConfigurableMongoDbMessageStore
extends AbstractConfigurableMongoDbMessageStore
implements MessageStore

An alternate MongoDB MessageStore and MessageGroupStore which allows the user to configure the instance of MongoTemplate. The mechanism of storing the messages/group of messages in the store is and is different from MongoDbMessageStore. Since the store uses serialization of the messages by default, all the headers, and the payload of the Message must implement Serializable interface

Since:

3.0

Method Details

addMessage

public <T> Message<T> addMessage(Message<T> message)

Description copied from interface: MessageStore

Put the provided Message into the MessageStore. The store may need to mutate the message internally, and if it does then the return value can be different than the input. The id of the return value will be used as an index so that the MessageStore.getMessage(UUID) and MessageStore.removeMessage(UUID) behave properly. Since messages are immutable, putting the same message more than once is a no-op.

Specified by:

addMessage in interface MessageStore

Type Parameters:

T - The payload type.

Parameters:

message - The message.

Returns:

The message that was stored.

removeMessage

public Message<?> removeMessage(UUID id)

Description copied from interface: MessageStore

Remove the Message with the given id from the MessageStore, if present, and return it. If no Message with that id is present in the store, this will return null.

Specified by:

removeMessage in interface MessageStore

Parameters:

id - THe message identifier.

Returns:

The message.

getMessageCount

public long getMessageCount()

Description copied from interface: MessageStore

Optional attribute giving the number of messages in the store. Implementations may decline to respond by throwing an exception.

Specified by:

getMessageCount in interface MessageStore

Returns:

The number of messages.

getMessageGroup

public MessageGroup getMessageGroup(Object groupId)

Description copied from interface: BasicMessageGroupStore

Return all Messages currently in the MessageStore that were stored using BasicMessageGroupStore.addMessageToGroup(Object, Message) with this group id.

Specified by:

getMessageGroup in interface BasicMessageGroupStore

Parameters:

groupId - The group identifier.

Returns:

A group of messages, empty if none exists for this key.

addMessageToGroup

public MessageGroup addMessageToGroup(Object groupId,
 Message<?> message)

Description copied from interface: BasicMessageGroupStore

Store a message with an association to a group id. This can be used to group messages together.

Specified by:

addMessageToGroup in interface BasicMessageGroupStore

Overrides:

addMessageToGroup in class AbstractMessageGroupStore

Parameters:

groupId - The group id to store the message under.

message - A message.

Returns:

The message group.

addMessagesToGroup

public void addMessagesToGroup(Object groupId,
 Message<?>... messages)

Description copied from interface: MessageGroupStore

Store messages with an association to a group id. This can be used to group messages together.

Specified by:

addMessagesToGroup in interface MessageGroupStore

Overrides:

addMessagesToGroup in class AbstractConfigurableMongoDbMessageStore

Parameters:

groupId - The group id to store messages under.

messages - The messages to add.

removeMessagesFromGroup

public void removeMessagesFromGroup(Object groupId,
 Collection<Message<?>> messages)

Description copied from interface: MessageGroupStore

Persist the deletion of messages from the group.

Specified by:

removeMessagesFromGroup in interface MessageGroupStore

Overrides:

removeMessagesFromGroup in class AbstractConfigurableMongoDbMessageStore

Parameters:

groupId - The groupId for the group containing the message(s).

messages - The messages to be removed.

pollMessageFromGroup

public Message<?> pollMessageFromGroup(Object groupId)

Description copied from interface: BasicMessageGroupStore

Poll Message from this MessageGroup (in FIFO style if supported by the implementation) while also removing the polled Message.

Specified by:

pollMessageFromGroup in interface BasicMessageGroupStore

Parameters:

groupId - The group identifier.

Returns:

The message.

setLastReleasedSequenceNumberForGroup
