Package org.graalvm.compiler.debug

Interface Summary

Interface	Description
CausableByCompilerAssert
CompilationListener	Implemented by clients interested in when the compiler starts/ends a phase or considers inlining a method.
CounterKey	A counter for some value of interest.
DebugCloseable	An AutoCloseable whose DebugCloseable.close() does not throw a checked exception.
DebugConfig
DebugContext.CompilerPhaseScope	Scope for a compiler phase event.
DebugContext.Scope	Represents a debug scope entered by DebugContext.scope(Object) or DebugContext.sandbox(CharSequence, DebugConfig, Object...).
DebugDumpHandler	Interface implemented by classes that provide an external visualization of selected object types such as compiler graphs and nodes.
DebugHandler	This interface exists to unify DebugDumpHandler and DebugVerifyHandler for the sake of DebugHandlersFactory.createHandlers(org.graalvm.compiler.options.OptionValues).
DebugHandlersFactory	Factory for creating DebugHandlers.
DebugMemUseTracker	Tracks memory usage within a scope using com.sun.management.ThreadMXBean.
DebugVerifyHandler	Performs some kind of verification on an object.
Indent	Object used to close a debug indentation scope.
JavaMethodContext	Interface for objects used in Debug context that can provide a JavaMethod.
MemUseTrackerKey	Tracks memory usage within a scope using com.sun.management.ThreadMXBean.
MetricKey	A key for a metric.
PathUtilitiesProvider	Defines a service for accessing storage resembling a file system.
TimerKey	A timer for some activity of interest.
TTYStreamProvider	Provides a PrintStream that writes to the underlying log stream of the VM.

Class Summary

Class	Description
Assertions	Utility for query whether assertions are enabled.
Assertions.Options
CloseableCounter	A helper class for AbstractKeys that can nest and need to split out accumulated and flat values for some kind of counter-like measurement.
CSVUtil	Utilities and global definitions for creating CSV output.
CSVUtil.Escape
DebugContext	A facility for logging and dumping as well as a container for values associated with MetricKeys.
DebugContext.Activation	An object used to undo the changes made by DebugContext#activate().
DebugContext.Builder	Object used to create a DebugContext.
DebugContext.Description	Describes the computation associated with a DebugContext.
DebugDumpScope
DebugOptions	Options that configure a DebugContext and related functionality.
DiagnosticsOutputDirectory	Manages a directory into which diagnostics such crash reports and dumps should be written.
GlobalMetrics	Metric values that can be updated by multiple threads.
KeyRegistry	Registry for allocating a globally unique integer id to each AbstractKey.
LogStream	A utility for printing compiler debug and informational output to an output stream.
MethodFilter	This class implements a method filter that can filter based on class name, method name and parameters.
PathUtilities	Miscellaneous methods for modifying and generating file system paths.
ScopeImpl
StandardPathUtilitiesProvider	A PathUtilitiesProvider implemented in terms of File and Path APIs.
TimeSource	A consistent source of timing data that should be used by all facilities in the debug package.
TTY	A collection of static methods for printing debug and informational output to a global LogStream.
TTY.Filter	Support for thread-local suppression of TTY.
Versions	Avoid using directly.

Enum Summary

Enum	Description
DebugOptions.PrintGraphTarget	Values for the DebugOptions.PrintGraph option denoting where graphs dumped as a result of the DebugOptions.Dump option are sent.

Error Summary

Error	Description
GraalError	Indicates a condition that should never occur during normal operation.
