Constructor Detail

ConcurrentCollectorMultiple

public ConcurrentCollectorMultiple()

Constructor that uses AbstractConcurrentCollector.DEFAULT_MAX_QUEUE_SIZE elements as the maximum queue length.

ConcurrentCollectorMultiple

public ConcurrentCollectorMultiple(@Nullable
                           IThrowingRunnableWithParameter<List<DATATYPE>> aPerformer)

Constructor that uses AbstractConcurrentCollector.DEFAULT_MAX_QUEUE_SIZE elements as the maximum queue length and DEFAULT_MAX_PERFORM_COUNT as the max perform count.

Parameters:

aPerformer - The callback to be invoked everytime objects are collected. May be null but in that case setPerformer(IThrowingRunnableWithParameter) must be invoked!

ConcurrentCollectorMultiple

public ConcurrentCollectorMultiple(@Nonnegative
                           int nMaxQueueSize,
                           @Nonnegative
                           int nMaxPerformCount,
                           @Nullable
                           IThrowingRunnableWithParameter<List<DATATYPE>> aPerformer)

Constructor.

Parameters:

nMaxQueueSize - The maximum number of items that can be in the queue. Must be > 0.

nMaxPerformCount - The maximum number of objects to be put in the queue for execution.

aPerformer - The callback to be invoked everytime objects are collected. May be null but in that case setPerformer(IThrowingRunnableWithParameter) must be invoked!
