Package org.apache.activemq.broker.region.policy

The policies which can be associated with a particular destination or wildcard.

Interface Summary

Interface	Description
DeadLetterStrategy	A strategy for choosing which destination is used for dead letter queue messages.
DispatchPolicy	Abstraction to allow different dispatching policies to be plugged into the topic region implementations.
DispatchSelector	Determines if a subscription can dispatch a message reference
MessageEvictionStrategy	A strategy for evicting messages from slow consumers.
MessageQuery	Represents some kind of query which will load initial messages from some source for a new topic subscriber.
PendingDurableSubscriberMessageStoragePolicy	Abstraction to allow different policies for holding messages awaiting dispatch to active clients
PendingMessageLimitStrategy	A pluggable strategy to calculate the maximum number of messages that are allowed to be pending on consumers (in addition to their prefetch sizes).
PendingQueueMessageStoragePolicy	Abstraction to allow different policies for holding messages awaiting dispatch on a Queue
PendingSubscriberMessageStoragePolicy	Abstraction to allow different policies for holding messages awaiting dispatch to active clients
SlowConsumerStrategy	Interface for a strategy for dealing with slow consumers
SubscriptionRecoveryPolicy	Abstraction to allow different recovery policies to be plugged into the region implementations.

Class Summary

Class	Description
AbortSlowAckConsumerStrategy	Abort slow consumers when they reach the configured threshold of slowness, default is that a consumer that has not Ack'd a message for 30 seconds is slow.
AbortSlowConsumerStrategy	Abort slow consumers when they reach the configured threshold of slowness, default is slow for 30 seconds
AbstractDeadLetterStrategy	A strategy for choosing which destination is used for dead letter queue messages.
ClientIdFilterDispatchPolicy	ClientIdFilterDispatchPolicy dispatches messages in a topic to a given client.
ConstantPendingMessageLimitStrategy	This PendingMessageLimitStrategy is configured to a constant value for all subscriptions.
DiscardingDeadLetterStrategy	A DeadLetterStrategy where each destination has its own individual DLQ using the subject naming hierarchy.
FilePendingDurableSubscriberMessageStoragePolicy	Creates a PendIngMessageCursor for Durable subscribers *
FilePendingQueueMessageStoragePolicy	Creates a FilePendingMessageCursor *
FilePendingSubscriberMessageStoragePolicy	Creates a PendIngMessageCursor for Durable subscribers *
FixedCountSubscriptionRecoveryPolicy	This implementation of SubscriptionRecoveryPolicy will keep a fixed count of last messages.
FixedSizedSubscriptionRecoveryPolicy	This implementation of SubscriptionRecoveryPolicy will keep a fixed amount of memory available in RAM for message history which is evicted in time order.
IndividualDeadLetterStrategy	A DeadLetterStrategy where each destination has its own individual DLQ using the subject naming hierarchy.
LastImageSubscriptionRecoveryPolicy	This implementation of SubscriptionRecoveryPolicy will only keep the last message.
MessageEvictionStrategySupport	A useful base class for implementation inheritence.
NoSubscriptionRecoveryPolicy	This SubscriptionRecoveryPolicy disable recovery of messages.
OldestMessageEvictionStrategy	An eviction strategy which evicts the oldest message first (which is the default).
OldestMessageWithLowestPriorityEvictionStrategy	An eviction strategy which evicts the oldest message with the lowest priority first.
PolicyEntry	Represents an entry in a PolicyMap for assigning policies to a specific destination or a hierarchical wildcard area of destinations.
PolicyMap	Represents a destination based configuration of policies so that individual destinations or wildcard hierarchies of destinations can be configured using different policies.
PrefetchRatePendingMessageLimitStrategy	This PendingMessageLimitStrategy sets the maximum pending message limit value to be a multiplier of the prefetch limit of the subscription.
PriorityDispatchPolicy	Priority dispatch policy that sends a message to every subscription that matches the message in consumer priority order.
PriorityNetworkDispatchPolicy	dispatch policy that ignores lower priority duplicate network consumers, used in conjunction with network bridge suppresDuplicateTopicSubscriptions
QueryBasedSubscriptionRecoveryPolicy	This implementation of SubscriptionRecoveryPolicy will perform a user specific query mechanism to load any messages they may have missed.
RetainedMessageSubscriptionRecoveryPolicy	This implementation of SubscriptionRecoveryPolicy will only keep the last non-zero length message with the ActiveMQMessage.RETAIN_PROPERTY.
RoundRobinDispatchPolicy	Simple dispatch policy that sends a message to every subscription that matches the message.
SharedDeadLetterStrategy	A default implementation of DeadLetterStrategy which uses a constant destination.
SimpleDispatchPolicy	Simple dispatch policy that sends a message to every subscription that matches the message.
SimpleDispatchSelector	Simple dispatch policy that determines if a message can be sent to a subscription
SlowConsumerEntry
StorePendingDurableSubscriberMessageStoragePolicy	Creates a PendingMessageCursor that access the persistent store to retrieve messages
StorePendingQueueMessageStoragePolicy	Creates a StoreQueueCursor *
StrictOrderDispatchPolicy	Dispatch policy that causes every subscription to see messages in the same order.
TimedSubscriptionRecoveryPolicy	This implementation of SubscriptionRecoveryPolicy will keep a timed buffer of messages around in memory and use that to recover new subscriptions.
UniquePropertyMessageEvictionStrategy	An eviction strategy which evicts the oldest message within messages with the same property value
VMPendingDurableSubscriberMessageStoragePolicy	Creates a VMPendingMessageCursor *
VMPendingQueueMessageStoragePolicy	Creates a VMPendingMessageCursor *
VMPendingSubscriberMessageStoragePolicy	Creates a VMPendingMessageCursor *
