run

protected void run(StructuredGraph graph,
                   CoreProviders context)

Specified by:

run in class BasePhase<CoreProviders>

applyIncremental

public void applyIncremental(StructuredGraph graph,
                             CoreProviders context,
                             Graph.Mark newNodesMark)

Parameters:

newNodesMark - only the new nodes specified by this mark are processed

applyIncremental

public void applyIncremental(StructuredGraph graph,
                             CoreProviders context,
                             Iterable<? extends Node> workingSet)

Parameters:

workingSet - the initial working set of nodes on which the canonicalizer works, should be an auto-grow node bitmap

hashCode

public int hashCode()

Description copied from class: BasePhase

Hashing a phase is used to implement and test phase plan serialization. Hashing a phase should take into account any fields that configure a phase. This will be done properly once a PhaseInfo annotation is introduced (c.f. NodeInfo). The hash code returned needs to be stable across VM executions.

Overrides:

hashCode in class BasePhase<CoreProviders>

equals

public boolean equals(Object obj)

Overrides:

equals in class BasePhase<CoreProviders>

See Also:

BasePhase.hashCode()

                               NodeClass<?> nodeClass,
