Method Detail

register

public CallCounter register(Object profKey)

Enabled: Note that multiple registrations of the same profKey will share the same CallCounter -- this is on purpose.

EMethodNode and Matcher use this my providing their printstring as the profKey, and pointing at the CallCounter. This means that multiple EMethodNodes with the same printstring will increment the same counters, and that the CallCounter object will not prevent these EMethodNodes from being garbage collected. A dynamic number of EMethodNodes with a static number of names will still only cause a static number of CallCounters to be allocated.

Should we start using multiple Java ClassLoaders, then we probably want to change JavaMemberNode and OverloaderNode to use the same trick.
