Method Summary

Modifier and Type	Method	Description
@NonNull List<? extends BasicBlock<?>>	getBlocksSorted()
@NonNull Collection<Stmt>	getNodes()	returns the nodes in this graph in a non-deterministic order (->Set) to get the nodes in linearized, ordered manner use iterator() or getStmts.
Stmt	getStartingStmt()
@NonNull List<Stmt>	getStartingStmts()
boolean	hasEdgeConnecting(@NonNull Stmt source, @NonNull Stmt target)	returns true if there is a flow between source and target throws an Exception if at least one of the parameters is not contained in the graph.
int	inDegree(@NonNull Stmt node)	returns the amount of ingoing flows into node
int	outDegree(@NonNull Stmt node)	returns the amount of flows that start from node
@NonNull List<Stmt>	predecessors(@NonNull Stmt node)	returns the ingoing flows to node as an List with no reliable/specific order and possibly duplicate entries i.e. if a JSwitchStmt has multiple cases that brnach to `node`
@NonNull List<Stmt>	successors(@NonNull Stmt node)	returns the outgoing flows of node as ordered List.

Overrides:

getBlocksSorted in class ForwardingStmtGraph

predecessors

public @NonNull List<Stmt> predecessors(@NonNull Stmt node)

Description copied from class: StmtGraph

returns the ingoing flows to node as an List with no reliable/specific order and possibly duplicate entries i.e. if a JSwitchStmt has multiple cases that brnach to `node`

Overrides:
