- All Implemented Interfaces:
Interceptor
public class BenchmarkInterceptor extends java.lang.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 can be seen here: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]]

beforeInvoke
public java.lang.Object beforeInvoke(java.lang.Object object, java.lang.String methodName, java.lang.Object[] arguments)
Description copied from interface:Interceptor
This code is executed before the method is optionally called.- Specified by:
beforeInvoke
in interfaceInterceptor
- Parameters:
object
- receiver object for the method callmethodName
- name of the method to callarguments
- arguments to the method call- Returns:
- any arbitrary result that replaces the result of the original method call only if doInvoke() returns false and afterInvoke() relays this result.
-
afterInvoke
public java.lang.Object afterInvoke(java.lang.Object object, java.lang.String methodName, java.lang.Object[] arguments, java.lang.Object result)
Description copied from interface:Interceptor
This code is executed after the method is optionally called.- Specified by:
afterInvoke
in interfaceInterceptor
- Parameters:
object
- receiver object for the called methodmethodName
- name of the called methodarguments
- arguments to the called methodresult
- result of the executed method call or result of beforeInvoke if method was not called- Returns:
- any arbitrary result that can replace the result of the original method call. Typically, the result parameter is returned.
-
doInvoke
public boolean doInvoke()
- Specified by:
doInvoke
in interfaceInterceptor
- Returns:
- whether the target method should be invoked at all.
-
statistic
public java.util.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]
