SBBreakpoint supports breakpoint location iteration, for example,

for bl in breakpoint:
|
|
print('breakpoint location load addr: %s' % hex(bl.GetLoadAddress()))
|
|
print('breakpoint location condition: %s' % hex(bl.GetCondition()))
|
|
|
|
and rich comparison methods which allow the API program to use,
|
|
|
|
if aBreakpoint == bBreakpoint:
|
|
...
|
|
|
|
to compare two breakpoints for equality."
