Constructor Details

QueueDescription

public QueueDescription(String path)

Initializes a new instance of QueueDescription with the specified relative path.

Parameters:

path -
  • Path of the topic. Max length is 260 chars. Cannot start or end with a slash. Cannot have restricted characters: '@','?','#','*'

Method Details

equals

public boolean equals(Object o)

Overrides:

QueueDescription.equals(Object o)

Parameters:

o

getAuthorizationRules

public List getAuthorizationRules()

Returns:

The AuthorizationRule on the queue to control user access at entity level.

getAutoDeleteOnIdle

public Duration getAutoDeleteOnIdle()

Returns:

The idle interval after which the queue is automatically deleted. Default value is MAX_DURATION

getDefaultMessageTimeToLive

public Duration getDefaultMessageTimeToLive()

Time-To-Live is the duration after which the message expires, starting from when the message is sent to Service Bus. This is the default value used when getTimeToLive() is not set on a message itself. Messages older than their TimeToLive value will expire and no longer be retained in the message store. Subscribers will be unable to receive expired messages.

Returns:

The default time to live value for the messages. Default value is MAX_DURATION

getDuplicationDetectionHistoryTimeWindow

public Duration getDuplicationDetectionHistoryTimeWindow()

Returns:

The duration of duplicate detection history that is maintained by the service. The default value is 1 minute.

getEntityStatus

public EntityStatus getEntityStatus()

Gets the status of the entity. When an entity is disabled, that entity cannot send or receive messages.

Returns:

The current status of the queue (Enabled / Disabled). The default value is Enabled.

getForwardDeadLetteredMessagesTo

public String getForwardDeadLetteredMessagesTo()

Returns:

The path of the recipient entity to which all the dead-lettered messages of this queue are forwarded to. If set, user cannot manually receive dead-lettered messages from this queue. The destination entity must already exist.

getForwardTo

public String getForwardTo()

Returns:

The path of the recipient entity to which all the messages sent to the queue are forwarded to. If set, user cannot manually receive messages from this queue. The destination entity must be an already existing entity.

getLockDuration

public Duration getLockDuration()

The amount of time that the message is locked by a given receiver so that no other receiver receives the same message.

Returns:

The duration of a peek lock. Default value is 60 seconds.

getMaxDeliveryCount

public int getMaxDeliveryCount()

The maximum delivery count of a message before it is dead-lettered. The delivery count is increased when a message is received in PEEKLOCK mode and didn't complete the message before the message lock expired.

Returns:

Default value is 10.

getMaxSizeInMB

public long getMaxSizeInMB()

Returns:

the maximum size of the queue in megabytes, which is the size of memory allocated for the queue. Default value is 1024.

getPath

public String getPath()

Returns:

The path of the queue.

getUserMetadata

public String getUserMetadata()

Returns:

Custom metdata that user can associate with the description.

hashCode

public int hashCode()

Overrides:

QueueDescription.hashCode()

isEnableBatchedOperations

public boolean isEnableBatchedOperations()

Returns:

Indicates whether server-side batched operations are enabled. Defaults to true.

public boolean isEnableDeadLetteringOnMessageExpiration()

Indicates whether this queue has dead letter support when a message expires.

Returns:

If true, the expired messages are moved to dead-letter sub-queue. Default value is false.

isEnablePartitioning

public boolean isEnablePartitioning()

Returns:

boolean indicating whether the queue is to be partitioned across multiple message brokers. Defaults to false
