Interface Summary

Interface	Description
Assumption	An assumption is a global boolean flag that starts with the value true (i.e., the assumption is valid) and can subsequently be invalidated (using Assumption.invalidate()).
CallTarget	Represents the target of a call.
InternalResource	Represents an internal resource of a language that can be lazily unpacked to a cache user directory.
ReplaceObserver	An observer that is notified whenever a child node is replaced.
RootCallTarget	Represents the target of a call to a RootNode, i.e., to another tree of nodes.
TruffleFile.FileTypeDetector	A detector for finding file's MIME type and encoding.
TruffleLanguage.ContextLocalFactory<C,T>	Context local factory for Truffle languages.
TruffleLanguage.ContextThreadLocalFactory<C,T>	Context thread local factory for Truffle languages.
TruffleOptionDescriptors	An OptionDescriptors enhanced to provide a sandbox policy for options.
TruffleRuntime	Interface representing a Truffle runtime object.
TruffleRuntimeAccess	A service that provides access to a TruffleRuntime implementation.
TruffleSafepoint.CompiledInterruptible<T>	Just like TruffleSafepoint.Interruptible but allows partial evaluation.
TruffleSafepoint.CompiledInterruptibleFunction<T,R>	Just like TruffleSafepoint.InterruptibleFunction but allows partial evaluation.
TruffleSafepoint.Interrupter	An interrupter allows a foreign thread to interrupt the execution on a separate thread.
TruffleSafepoint.Interruptible<T>	Function interface that represent interruptable Java methods.
TruffleSafepoint.InterruptibleFunction<T,R>	Function interface that represent interruptable Java methods.

Class Summary

Class	Description
ArrayUtils	This class provides additional operations for String as well as character and byte arrays, which may be intrinsified by a compiler.
CompilerAsserts	Assertions about the code produced by the Truffle compiler.
CompilerDirectives	Directives that influence the optimizations of the Truffle compiler.
ContextLocal<T>	A context local reference that refers to a value that is created for each polyglot context.
ContextThreadLocal<T>	A context thread local reference that refers to a value that is created for each polyglot context and thread.
ExactMath	This class contains exact math related methods that are generally useful for dynamic language implementations.
HostCompilerDirectives	Directives that influence the optimizations of the host compiler.
InstrumentInfo	Represents public information about an instrument.
InternalResource.Env	Access to common utilities for unpacking resource files.
ThreadLocalAction	Represents an action that is executed at a safepoint location of the guest language execution.
ThreadLocalAction.Access	Argument class for ThreadLocalAction.perform(Access).
Truffle	Class for obtaining the Truffle runtime singleton object of this virtual machine.
TruffleContext	A handle on a context of a set of Truffle languages.
TruffleFile	An abstract representation of a file used by Truffle languages.
TruffleFile.AttributeDescriptor<T>	Represents a file's attribute.
TruffleFile.Attributes	A view over file's attributes values obtained by getAttributes.
TruffleLanguage<C>	A Truffle language implementation contains all the services a language should provide to make it composable with other languages.
TruffleLanguage.ContextLocalProvider<C>	Provider for creating context local and context thread local references.
TruffleLanguage.ContextReference<C>	Represents a reference to the current context.
TruffleLanguage.Env	Represents execution environment of the TruffleLanguage.
TruffleLanguage.InlineParsingRequest	Request for inline parsing.
TruffleLanguage.LanguageReference<L extends TruffleLanguage>	Represents a reference to the current language instance.
TruffleLanguage.ParsingRequest	Request for parsing.
TruffleLogger	Support for logging in Truffle languages and instruments.
TruffleOptions	Class containing general Truffle options.
TruffleSafepoint	Truffle safepoints allow interrupting the guest language execution to execute thread-local actions submitted by a language or tool.
TruffleStackTraceElement	Represents a guest stack trace element.
TruffleThreadBuilder	A builder for threads that have access to the appropriate TruffleContext.

Enum Summary

Enum	Description
InternalResource.CPUArchitecture	Represents a supported CPU architecture.
InternalResource.OS	Represents a supported operating system.
TruffleLanguage.ContextPolicy	Defines the supported policy for reusing languages per context.
TruffleLanguage.ExitMode	Mode of exit operation.

Exception Summary

Exception	Description
OptimizationFailedException
TruffleStackTrace	Represents a guest language stack trace.

Annotation Types Summary

Annotation Type	Description
CompilerDirectives.CompilationFinal	Marks fields that should be considered final for a Truffle compilation although they are not final while executing in the interpreter.
CompilerDirectives.TruffleBoundary	Marks a method that it is considered as a boundary for Truffle partial evaluation.
CompilerDirectives.ValueType	Marks classes as value types.
HostCompilerDirectives.BytecodeInterpreterSwitch	Marks a method that is an implementation of a Truffle interpreter, and which should receive additional optimization budget.
HostCompilerDirectives.InliningCutoff	Hints to Truffle host inlining that a particular method is partial evaluatable, but it would be a good place for a cutoff when performing host inlining.
InternalResource.Id	The annotation used to lookup InternalResource by an id.
Option	Describes the attributes of an option whose value is in a static field annotated by this annotation.
Option.Group	Must be applied on classes containing option fields to specify a name prefix if the prefix cannot be inferred by language or instrument.
TruffleLanguage.Registration	The annotation to use to register your language to the Polyglot API.
