Examples ( How to use this example )
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.
