[cdt-dev] DSF stack frame levels vs indexes

["Mario Pierro" <Mario.Pierro@xxxxxxx>]

Hello,

I am trying to understand the caching mechanism used by DSF 2.0 when
retrieving stack frames. Apparently for caching to work stack frames
only need to be compared by their level - at least, that's what the GDB
implementation does in MIFrameDMC.equals().

I have the following questions:

1. What should the getLevel() method implementation report? Is that the
number of valid stack frames that precede a given frame in the call
stack? 

2. What is the relation between the indexes passed to

public void getFrames(IDMContext execContext, int startIndex, int
endIndex, DataRequestMonitor<IFrameDMContext[]> rm);

and stack frame levels?

Thanks for your help!

Best,

/Mario
