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 Update 3 or later installed.
