Exception Summary

Exception	Description
UnsupportedSpecializationException	Thrown by the generated code of Truffle-DSL if no compatible Specialization could be found for the provided values.

Annotation Types Summary

Annotation Type	Description
Bind	Binds and executes an expression at most once for every execution of the node.
Cached	A parameter annotated with Cached in a Specialization refers to a cached value of a specialization instance.
Cached.Exclusive	Disallows any sharing with other cached parameters.
Cached.Shared	Allows sharing between multiple Cached parameters between multiple specializations or exported library messages.
CreateCast	Specifies a factory method that creates a Node which is used to cast this child.
Executed	This annotation declares a child field to be executed and used as dynamic input values for specializations.
Fallback	A method annotated with Fallback is treated as a Specialization that implicitly links all the guards of all other declared Specialization annotated methods of the operation in a negated form.
GenerateAOT	Allows nodes with specializations to be prepared for AOT.
GenerateAOT.Exclude	Excludes the annotated Specialization from AOT preparation.
GenerateCached	Allows to enable or disable the generation of the cached version of a Truffle DSL node.
GeneratedBy	Marks a type as being generated based on another class or method of a class.
GenerateInline	Generates code for a node that makes this node inlinable when used in cached parameters of specializations.
GenerateNodeFactory	Annotate nodes or base classes of nodes to generate factory handlers implementing the NodeFactory interface.
GeneratePackagePrivate	Make the code generated for an annotated node package-private.
GenerateUncached	Generates an uncached version of a node with specializations.
Idempotent	Methods annotated with Idempotent must be methods that may cause side effects but will always cause the same side effects for repeated invocations with the same parameters.
ImplicitCast	Marks an implicit cast method.
ImportStatic	Imports all public and static methods and fields of the provided classes for the use in DSL expressions of the annotated class or its subclasses.
InlineSupport.RequiredField	Used to specify fields for node object inlining in inline methods for the inline target.
InlineSupport.RequiredFields	Used to specify multiple InlineSupport.RequiredField.
InlineSupport.UnsafeAccessedField	Marks a field to be accessed with unsafe.
Introspectable	Annotate a DSL operation using this annotation to be introspectable.
NeverDefault	Useful to annotate methods, fields or parameters bound by any DSL expression to indicate that it never returns a null or default primitive value.
NodeChild	A NodeChild element defines an executable child for the enclosing Node.
NodeChildren
NodeField	A NodeField element defines a field for the generated Node.
NodeFields	A NodeFields element defines a field for the generated Node.
NonIdempotent	Methods annotated with NonIdempotent must be methods that may cause side effects but may not always cause the same side effects for repeated invocations with the same parameters.
ReportPolymorphism	Enables reporting of polymorphic specializations from this node or exported message to the runtime.
ReportPolymorphism.Exclude	Nodes (and their subclasses) or specializations annotated with this annotation will be excluded from consideration when reporting polymorphic specializations.
ReportPolymorphism.Megamorphic	Specializations annotated with this annotation are considered megamorphic.
Specialization	Defines a method of a node subclass to represent one specialization of an operation.
SpecializationStatistics.AlwaysEnabled	Used on nodes to always enable specialization statistics.
SuppressPackageWarnings	Use to suppress Truffle DSL warnings in whole packages using a package-info.java class.
TypeCast	Overrides the standard way of casting a certain type in a TypeSystem.
TypeCheck	Overrides the standard way of checking for a certain type in a TypeSystem.
TypeSystem	Type guards are the most common form of guards used in Truffle languages.
TypeSystemReference	References a TypeSystem on a node.
