[lldb-dev] SBValue defined vs runtime type

[jingham at apple.com]

As long as the variable we're printing remains in scope, you should be able to change your mind about what you want to fetch and we'll refresh the object.  You can see this for instance in the Script interpreter:

>>> print var.GetType()
Dynamic:
FooChild *
Static:
Foo *
>>> print var.SetPreferDynamicValue(lldb.eNoDynamicValues)
None
>>> print var.GetType()
Foo *
>>> print var.SetPreferDynamicValue(lldb.eDynamicCanRunTarget)
None
>>> print var.GetType()
Dynamic:
FooChild *
Static:
Foo *

Once the value is no longer alive in the target (e.g. it was a local and you stepped out of that local's frame) then we won't be able to fetch any more information about it and you're stuck with what you asked for.
