Method Summary

Modifier and Type	Method and Description
boolean	canBeProvenSafe(Class<?> clazz) Return true if the class is allowed to be proven safe.
boolean	checkDelayedInitialization() Check that all registered classes are here, regardless if the AnalysisType got actually marked as used.
Set<Class<?>>	classesWithKind(InitKind kind) Returns all classes of a single InitKind.
void	forceInitializeHosted(Class<?> clazz, String reason, boolean allowInitializationErrors) Initializes the class during image building, and reports an error if the user requested to delay initialization to runtime.
void	maybeInitializeHosted(jdk.vm.ci.meta.ResolvedJavaType type) Initializes the class during image building, unless initialization must be delayed to runtime.
String	objectInstantiationTraceMessage(Object obj, String action)
String	reasonForClass(Class<?> clazz)
void	setConfigurationSealed(boolean sealed)
void	setProvenSafeLate(Set<Class<?>> initializeSafeDelayedClasses)
void	setUnsupportedFeatures(com.oracle.graal.pointsto.constraints.UnsupportedFeatures o)
boolean	shouldInitializeAtRuntime(Class<?> clazz) Returns true if the provided class should be initialized at runtime.
boolean	shouldInitializeAtRuntime(jdk.vm.ci.meta.ResolvedJavaType type) Returns true if the provided type should be initialized at runtime.

Method Detail

specifiedInitKindFor

InitKind specifiedInitKindFor(Class<?> clazz)

Returns an init kind for clazz.

canBeProvenSafe

boolean canBeProvenSafe(Class<?> clazz)

Return true if the class is allowed to be proven safe.

classesWithKind

Set<Class<?>> classesWithKind(InitKind kind)

Returns all classes of a single InitKind.

shouldInitializeAtRuntime

boolean shouldInitializeAtRuntime(jdk.vm.ci.meta.ResolvedJavaType type)

Returns true if the provided type should be initialized at runtime.

shouldInitializeAtRuntime

boolean shouldInitializeAtRuntime(Class<?> clazz)

Returns true if the provided class should be initialized at runtime.

maybeInitializeHosted

void maybeInitializeHosted(jdk.vm.ci.meta.ResolvedJavaType type)

Initializes the class during image building, unless initialization must be delayed to runtime.

forceInitializeHosted

void forceInitializeHosted(Class<?> clazz,
                           String reason,
                           boolean allowInitializationErrors)

Initializes the class during image building, and reports an error if the user requested to delay initialization to runtime.

checkDelayedInitialization

boolean checkDelayedInitialization()

Check that all registered classes are here, regardless if the AnalysisType got actually marked as used. Class initialization can have side effects on other classes without the class being used itself, e.g., a class initializer can write a static field in another class.

setUnsupportedFeatures

void setUnsupportedFeatures(com.oracle.graal.pointsto.constraints.UnsupportedFeatures o)

setConfigurationSealed

void setConfigurationSealed(boolean sealed)

objectInstantiationTraceMessage

String objectInstantiationTraceMessage(Object obj,
                                       String action)

reasonForClass

String reasonForClass(Class<?> clazz)

setProvenSafeLate

void setProvenSafeLate(Set<Class<?>> initializeSafeDelayedClasses)
