All Implemented Interfaces:

Callback

public class PropertiesQuantilesCallback
extends QuantilesCallback

Callback which stores data in buckets to compute quantiles. Buckets are created from configuration stored in a Properties file. Configuration file should look like:

 # Global default values are set on root
 .min=0
 .max=60000
 .nb=5
 .type=LINEAR

 # For org.javasimon group: more buckets
 org.javasimon.nb=10

 # SlowClass is a performance bottleneck: higher upper bound
 org.javasimon.slow.SlowClass.max=300000

 # Can use Exponential buckets for some Stopwatches
 org.javasimon.special.type=EXPONENTIAL
