The New Profiler is a type of activating profiler which
records the creation of new instances.
The New Profiler patches the basicNew[:[max:]]
methods of Behaviour, so when a new instance is created through
the following code:
Array new: 10
An entry will be recorded indicating that a new Array was
created, with an indexed size of 10. The profiler will
additionally try and record the user method which made this call.
This simply searches back on the current stack, and currently
will often simply point to a system method which may not
elucidate the context sufficiently.
Objects can be created within Dolphin through the actions of primitives other from that which is called by the basicNew methods. Some
examples include Number>>@, the core Float and LargeInteger
methods, Object>>shallowCopy. Presently these objects will
not be registered, though it could be possible to extend the
profiler to also patch those methods which interest you.
A further point is that it may be possible to modify the size
of an objects indexed variables after it has been created with the
Object>>resize: method. This can be reflected in inaccurate
statistics results.
The raw collected details are visible in the Profile Browser. A statistical
view is provided by the New
Statistics view.
