Class BenchmarkInterceptor
- java.lang.Object
- 
- groovy.lang.BenchmarkInterceptor
 
- 
- All Implemented Interfaces:
- Interceptor
 
 public class BenchmarkInterceptor extends Object implements Interceptor Interceptor that registers the timestamp of each method call before and after invocation. The timestamps are stored internally and can be retrieved through the with thegetCalls() andstatistic() API.Example usage: def proxy = ProxyMetaClass.getInstance(ArrayList.class) proxy.interceptor = new BenchmarkInterceptor() proxy.use { def list = (0..10000).collect{ it } 4.times { list.size() } 4000.times { list.set(it, it+1) } } proxy.interceptor.statistic()Which produces the following output:[[size, 4, 0], [set, 4000, 21]]

getCallspublic Map getCalls() Returns the raw data associated with the current benchmark run.

resetpublic void reset() Resets all the benchmark data on this object.
 - 
beforeInvokepublic Object beforeInvoke(Object object, String methodName, Object[] arguments) This code is executed before the method is called.- Specified by:
- beforeInvokein interface- Interceptor
- Parameters:
- object- receiver object for the method call
- methodName- name of the method to call
- arguments- arguments to the method call
- Returns:
- null relays this result.
 
 - 
afterInvokepublic Object afterInvoke(Object object, String methodName, Object[] arguments, Object result) This code is executed after the method is called.- Specified by:
- afterInvokein interface- Interceptor
- Parameters:
- object- receiver object for the called method
- methodName- name of the called method
- arguments- arguments to the called method
- result- result of the executed method call or result of beforeInvoke if method was not called
- Returns:
- result
 
 - 
doInvokepublic boolean doInvoke() The call should be invoked separately- Specified by:
- doInvokein interface- Interceptor
- Returns:
- true
 
 - 
statisticpublic List statistic() Returns benchmark statistics as a List<Object[]>. AccumulateTime is measured in milliseconds and is as accurate as System.currentTimeMillis() allows it to be.- Returns:
- a list of lines, each item is [methodname, numberOfCalls, accumulatedTime]
