Method Details

getReturnStatementStores

List<Pair<ReturnNode,@Nullable TransferResult<V,S>>> getReturnStatementStores()

Get stores at return statements. These stores are transfer results at return node. Thus for a forward analysis, these stores contain the analyzed flow information from entry nodes to return nodes.

Returns:

the transfer results for each return node in the CFG
