Constructor Detail

MutableLongStats

public MutableLongStats(long... distribution)

Note: do not use distribution when accept(long) frequency is in nanos ( <<< 1 millis).

Parameters:

distribution - is a list of long values, which are used to create distribution ranges for the long values consumed by this MutableLongStats via accept(long). For example:: if you pass in the following params: (1, 10, 100), the distributionStats map will contain the following entries:

• key: 1, value: counter for all accepted accept(long) long values in range: (-infinity, 1L]
• key: 10, value: counter for all accepted accept(long) long values in range: (1L, 10L]
• key: 100, value: counter for all accepted accept(long) long values in range: (10L, 100L]
• key: LongStats.MAX_DISTRIBUTION, value: counter of all accepted accept(long) long values in range: (100L, +infinity)
