Interprocedural dataflow analysis

Hi,

While trying to create a detector which does some dataflow analysis, I
found out that the detector needs to do some inter-procedural analysis.
FindBugs' dataflow analysis framework seems to be used only for
intra-procedural analysis.

Is it possible to use the current FindBugs dataflow framework to do
inter-procedural dataflow analysis or is it only really suited for
intra-procedural analysis?
