SampleTypesExample.as

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.
