Method Detail

addGraphEdges

public static void addGraphEdges(Cfg originalGraph,
                 CfgNode<?> originalNode,
                 CfgNode<?> newStartNode,
                 CfgNode<?> newEndNode,
                 Cfg newSubgraph)

createGraphBottomAssumptions

public static <A extends Assumption<?>> SubgraphAssumptions<A> createGraphBottomAssumptions(Cfg graph)

createSingleNodeReplacementGraph

public static Cfg createSingleNodeReplacementGraph(Cfg originalGraph,
                                   CfgNode<?> originalNode,
                                   CfgNode<?> newNode)

Create a graph with single node. Resulting graph will have same amount of input/output edges as the original node.

findContainingStatement

public static CfgNode<?> findContainingStatement(CfgNode<?> node)

Find CFG node corresponding to the nearest statement, containing the AST node of the passed node.

findParentOfContainingStatement

public static CfgNode<?> findParentOfContainingStatement(CfgNode<?> node)

Find parent of containing statement.
