org.graalvm.polyglot (GraalVM Truffle Java API Reference)

Class Summary
Class	Description
Context	A polyglot context for Graal guest languages that allows to `evaluate` code.
Engine	An execution engine for Graal guest languages that allows to inspect the the installed `guest languages`, `instruments` and their available options.
EnvironmentAccess	Represents an access policy to the process environment for the guest languages of a context.
HostAccess	Represents the host access policy of a polyglot context.
Instrument	A handle for an instrument installed in an `engine`.
Language	A handle for a Graal language installed in an `engine`.
PolyglotAccess	Represents an access policy for polyglot builtins in the guest languages.
ResourceLimitEvent	Event triggered by a resource limit for a context.
ResourceLimits	Represents resource limits configuration that is used to configure contexts.
Source	Representation of a source code unit and its contents that can be evaluated in an execution `context`.
SourceSection	Description of contiguous section of text within a `Source` of program code.; supports multiple modes of access to the text and its location.
TypeLiteral<T>	Represents a generic type `T`.
Value	Represents a polyglot value that can be accessed using a set of language agnostic operations.

Enum Summary
Enum	Description
HostAccess.MutableTargetMapping	List of default host object mappings of mutable target types available in `Value.as(Class)`.
HostAccess.TargetMappingPrecedence	Represents the precedence of a target type mapping.
SandboxPolicy	The sandbox policy presets and validates configurations of a `context` or `engine` to be suitable as a code sandbox.

Exception Summary
Exception Description

PolyglotException
A polyglot exception represents errors that contain Graal guest languages on the stack trace.

Exception Summary
Exception	Description
PolyglotException	A polyglot exception represents errors that contain Graal guest languages on the stack trace.

Annotation Types Summary
Annotation Type	Description
HostAccess.DisableMethodScoping	If `HostAccess.SCOPED` is used, placing this annotation on an exported host function excludes it from parameter scoping, i.e.
HostAccess.Export	Annotation used by the predefined `HostAccess.EXPLICIT` access policy to mark public constructors, methods and fields in public classes that should be accessible by the guest application.
HostAccess.Implementable	Allows guest language to implement a Java type.

Package org.graalvm.polyglot Description

The GraalVM SDK polyglot API allows to embed Graal languages in Java applications.

To get started quickly create a new Context using Context.create(String...) and then evaluate guest language code using Context.eval(String, CharSequence).

See graalvm.org for more examples on how to use this API.
