org.checkerframework.dataflow.cfg.node.AbstractNodeVisitor<TransferResult<UnusedAbstractValue,ReachingDefinitionStore>,TransferInput<UnusedAbstractValue,ReachingDefinitionStore>>

org.checkerframework.dataflow.reachingdef.ReachingDefinitionTransfer

All Implemented Interfaces:

ForwardTransferFunction<UnusedAbstractValue,ReachingDefinitionStore>, TransferFunction<UnusedAbstractValue,ReachingDefinitionStore>, NodeVisitor<TransferResult<UnusedAbstractValue,ReachingDefinitionStore>,TransferInput<UnusedAbstractValue,ReachingDefinitionStore>>

public class ReachingDefinitionTransfer
extends AbstractNodeVisitor<TransferResult<UnusedAbstractValue,ReachingDefinitionStore>,TransferInput<UnusedAbstractValue,ReachingDefinitionStore>>
implements ForwardTransferFunction<UnusedAbstractValue,ReachingDefinitionStore>

The reaching definition transfer function. The transfer function processes the ReachingDefinitionNode in ReachingDefinitionStore, killing the node with same LHS and putting new generated node into the store. See dataflow manual for more details.
