All Implemented Interfaces:

PhaseSizeContract

public class FinalCanonicalizerPhase
extends CanonicalizerPhase

Final application of CanonicalizerPhase. After the application of this phase, no further canonicalizations should be made to a StructuredGraph. See CanonicalizerTool.finalCanonicalization() for more details.

canApply

public Optional<BasePhase.NotApplicable> canApply(GraphState graphState)

Description copied from class: BasePhase

Checks if all the preconditions to BasePhase.apply(StructuredGraph, Object, boolean) the phase are met.

Overrides:

canApply in class CanonicalizerPhase

Parameters:

graphState - represents the state of the StructuredGraph used for compilation and contains the required information to determine if a phase can be applied.

Returns:

Optional.empty() if all the checks pass, Optional#of(NotApplicable) containing why this phase is not applicable on this graphState otherwise.

updateGraphState

public void updateGraphState(GraphState graphState)

Description copied from class: BasePhase

Applies all the changes on the GraphState caused by BasePhase.apply(StructuredGraph, Object, boolean).

Overrides:

updateGraphState in class CanonicalizerPhase

Parameters:

graphState - represents the state of the StructuredGraph used for compilation.
