Methods

Modifier and Type	Method and Description
void	applyPreMeetHandler() Initialize this data flow node to compute the new solution This is done before iteratively calling the MEET operator.
void	applyTransferFunction(Instr i) Apply transfer function to the instruction
void	boxVar(org.jruby.ir.dataflow.analyses.UnboxableOpsAnalysisNode.UnboxState state, Class reqdType, Map<Variable,TemporaryLocalVariable> unboxMap, Variable v, List<Instr> newInstrs)
void	buildDataFlowVars(Instr i) Builds the data-flow variables (or facts) for a particular instruction.
void	compute_MEET(org.jruby.dirgra.Edge e, UnboxableOpsAnalysisNode pred) "MEET" current solution of "IN/OUT" with "OUT/IN(pred)", where "pred" is a predecessor of the current node! The choice of "IN/OUT" is determined by the direction of data flow.
void	finalizeSolution() Any required cleanup of state after applying transfer function
void	init() Initialize this data flow node for solving the current problem This is done after building dataflow variables for the problem.
void	initSolution() Any setting up of state/initialization before applying transfer function
boolean	solutionChanged() Did dataflow solution for this node change from last time?
String	toString()
