List of all members.


Detailed Description

Management of the CPU profiling results snapshot. A CPU snapshot is created from the runtime CCTs for all profiled threads, that are provided by CPUCallGraphBuilder. Initially it contains only these same (logically) CCTs (in instances of CPUCCTContainer), but in compact "flattened" format that takes less space in memory, and represented in microseconds, cleansed time. When the user starts to open CCT nodes for the given thread, the relevant objects (PrestimeCPUCCTNodes) are generated lazily for touched nodes out of the initial compact representation. This is done via a PrestimeCPUCCTNode object keeping a pointer into the compact tree representation where its data is located, from which the data for its children can be located, etc. When the user requests data in different "view" (switching say from method-level to class- (or package-) level aggregation), the relevant compact representation for all threads is generated out of the initial compact representation.
