The behavior of this function depends on the implementation ( it may be necessary to check whether
in1 and in2 are equal or aliased ).

This function often causes confusion, because the same interface is used
for both forward and backward flow analyses. The first parameter is
always the argument to the flow function (i.e. it is the "in" set in a
forward analysis and the "out" set in a backward analysis), and the third
parameter is always the result of the flow function (i.e. it is the "out"
set in a forward analysis and the "in" set in a backward analysis).flowThrough in class FlowAnalysis<Unit,java.util.BitSet>in - the input flowunit - the current nodeout - the returned flowprotected void copy(java.util.BitSet source,
