DynamicNewInstanceTypeFlow(BytecodePosition location, TypeFlow<?> newTypeFlow, AnalysisType type)

Method Summary

Modifier and Type	Method and Description
AnalysisContext	allocationContext()
boolean	canSaturate() Can this type flow saturate? By default all type flows can saturate, with the exception of a few ones that need to track all their types, e.g., AllInstantiated, AllSynchronized, etc.
TypeFlow<BytecodePosition>	copy(PointsToAnalysis bb, MethodFlowsGraph methodFlows) By default a type flow is not cloneable.
void	initFlow(PointsToAnalysis bb) Initialization code for some type flow corner cases.
boolean	needsInitialization() Type flows that require initialization after the graph is created need to override this method and return true.
void	onObservedSaturated(PointsToAnalysis bb, TypeFlow<?> observed) Notified by an observed flow that it is saturated.
void	onObservedUpdate(PointsToAnalysis bb) Notify the observer that the observed type flow state has changed.
void	setObserved(TypeFlow<?> declaredTypeFlow) Set the type flow that this flow is observing.
String	toString()

Constructor Detail

DynamicNewInstanceTypeFlow

public DynamicNewInstanceTypeFlow(BytecodePosition location,
                                  TypeFlow<?> newTypeFlow,
                                  AnalysisType type)

Method Detail

copy

public TypeFlow<BytecodePosition> copy(PointsToAnalysis bb,
                                       MethodFlowsGraph methodFlows)

Description copied from class: TypeFlow

By default a type flow is not cloneable.

Overrides:

copy in class TypeFlow<BytecodePosition>

initFlow

public void initFlow(PointsToAnalysis bb)

Description copied from class: TypeFlow

Initialization code for some type flow corner cases. TypeFlow.needsInitialization() also needs to be overridden to enable type flow initialization.

Overrides:

initFlow in class TypeFlow<BytecodePosition>

needsInitialization

public boolean needsInitialization()

Description copied from class: TypeFlow

Type flows that require initialization after the graph is created need to override this method and return true.

Overrides:

needsInitialization in class TypeFlow<BytecodePosition>

onObservedUpdate

public void onObservedUpdate(PointsToAnalysis bb)

Description copied from class: TypeFlow

Notify the observer that the observed type flow state has changed.

Overrides:

onObservedUpdate in class TypeFlow<BytecodePosition>

allocationContext

public AnalysisContext allocationContext()

setObserved

public void setObserved(TypeFlow<?> declaredTypeFlow)

Description copied from class: TypeFlow

Set the type flow that this flow is observing.

Overrides:

setObserved in class TypeFlow<BytecodePosition>

onObservedSaturated

public void onObservedSaturated(PointsToAnalysis bb,
                                TypeFlow<?> observed)

Description copied from class: TypeFlow

Notified by an observed flow that it is saturated.

Overrides:

onObservedSaturated in class TypeFlow<BytecodePosition>

canSaturate

public boolean canSaturate()

Description copied from class: TypeFlow

Can this type flow saturate? By default all type flows can saturate, with the exception of a few ones that need to track all their types, e.g., AllInstantiated, AllSynchronized, etc.

Overrides:

canSaturate in class TypeFlow<BytecodePosition>

toString

public String toString()

Overrides:

toString in class TypeFlow<BytecodePosition>
