Method Detail

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object

getMaxQueueLength

public int getMaxQueueLength()

Return the maximum numbers of tuples that this queue has ever seen.

Returns:

maximum number of tuples that this queue can contain

getCurrentQueueLength

public int getCurrentQueueLength()

Return the approximate number of tuples currently in this queue. This number is approximate since there can be multiple threads accessing the queue at the same time.

Returns:

the approximate number of tuples currently in the queue

getBatchProcessingTime

public int getBatchProcessingTime()

Return the a moving average of the amount of time (microseconds) that it takes to process a batch of tuples.

Returns:

amount of time (microseconds) that it takes to process a batch of tuples

Since:

6.3.10

getBatchLatency

public int getBatchLatency()

Return a moving average of the time (microseconds) for a batch of tuples to traverse the queue

Returns:

amount of time (microseconds) for a batch of tuples to traverse the queue

Since:

6.3.10

getBatchSize

public long getBatchSize()

Return a moving average of the size of a batch of tuples

Returns:

Return a moving average of the size of a batch of tuples

Since:

6.6.13

getName

public String getName()

Return the name of this queue. For queues between modules the name will be the name of the stream that is being enqueued into. For queues between containers the name will be the name of the container connection.

Returns:

the name of this queue

clear

void clear()

clone

public Object clone()

Overrides:

clone in class Object
