Tracking the number of put/get methods on Map using the Java API -

-

how can track number of calls on , put methods on map?.

i have seen somewhere jprofiler, must know if problem can solved using java api itself.

couple of options come mind.

  • if don't want change source code of application introspection way go. use profiler method invocations , see how these methods invoked. visualvm, jprofiler , others.

  • if don't want use external application needs hook in aspect oriented programming. example aspectj. configure aspect method entries , log results.

  • if want log calls own api can write wrapper around map implementation of choie , log invocations. of course need custom wrapper map related operations.
