The following example uses the
stack
and
time
properties of a Sample object
s
to collect memory samples. The samples contain NewObjectSample objects (the
newSamples
array), DeleteObjectSample objects (the
delSamples
array), and CPU memory sample
objects (the
cpuSamples
array). To use
the memory profiler, you need to have Flash Player debugger version 9.0.115.0 or later installed.
