Profiling Results - Memory Usage - Object Allocations
The Object Allocation tab displays the results when you select the Record Object Creation option in the
Analyze Memory Usage command or Memory Profiling in the
Custom Profile.
The Object Allocation tab opens in the Profiling Results tab when you click
Get Current Results ( 
) in the Profiler window.
The Object Allocation tab displays a list of classes
(including array classes), with the total size and number of instances that have
been allocated since you issued the instrumentation command. You can bring up a
reverse call graph with all call paths leading to object allocations for the given
class and locate the source code for objects.
To bring up a reverse call graph and locate the source code for a method
- In the Object Allocation tab, double-click on a class, or right-click on a class and choose Show Allocations Stack Traces from the contextual menu
This brings up the Allocation Paths tab with the reverse call graph. This information can help you
determine which call paths contribute most of the allocated objects.
- In the Allocation Paths tab, double-click on a method item, or right-click a method item and choose Go to Source... from the contextual menu
The source code for the method opens up in a new tab in the Source Editor.
Object Allocation measuring in Profiler
The number of object allocations that Profiler presents is exact, whereas
both the total object size and the reverse call graphs are by default
obtained statistically. This is one of the many performance improvement
measures available in the Profiler. See
how it works.
