Class SimpleProfileRepository

java.lang.Object
  org.multiverse.utils.profiling.SimpleProfileRepository

All Implemented Interfaces:

ProfileRepository

public final class SimpleProfileRepository
extends java.lang.Object
implements ProfileRepository

A simple ProfileRepository implementation.

Improvements needed:

1. composedkey is created even for lookup. Object creation is slow so this unwanted object creation should be removed
2. The ConcurrentHashMap still needs locking (even though it used striped locks), so perhaps a non blocking version could improve performance
