Method Detail

initialValue

public CounterConfiguration.Builder initialValue(long initialValue)

Sets the initial value.

The default value is zero.

Parameters:

initialValue - the new initial value.

lowerBound

public CounterConfiguration.Builder lowerBound(long lowerBound)

Sets the lower bound (inclusive) of the counter.

Only for CounterType.BOUNDED_STRONG counters.

The default value is Long.MIN_VALUE.

Parameters:

lowerBound - the new lower bound.

upperBound

public CounterConfiguration.Builder upperBound(long upperBound)

Sets the upper bound (inclusive) of the counter.

Only for CounterType.BOUNDED_STRONG counters.

The default value is Long.MAX_VALUE.

Parameters:

upperBound - the new upper bound.

storage

public CounterConfiguration.Builder storage(Storage storage)

Sets the storage mode of the counter.

The default value is Storage.VOLATILE.

Parameters:

storage - the new storage mode.

concurrencyLevel

public CounterConfiguration.Builder concurrencyLevel(int concurrencyLevel)

Sets the concurrency level of the counter.

Only for CounterType.WEAK.

The concurrency level set the amount of concurrent updates that can happen simultaneous. It is trade-off between the write performance and read performance. A higher value will allow more concurrent updates, however it will take more time to compute the counter value.

The default value is 64.

Parameters:

concurrencyLevel - the new concurrency level.

build

public CounterConfiguration build()

Returns:

the CounterConfiguration with this configuration.
