Interface Summary

Interface	Description
CelAttributeResolver	Resolver for attribute lookups at runtime.
CelEvaluationListener	Functional interface for a callback method invoked by the runtime.
CelFunctionOverload	Interface describing the general signature of all CEL custom function implementations.
CelFunctionOverload.Binary<T1,T2>	Helper interface for describing binary functions where the type parameters are used to improve compile-time correctness of function bindings.
CelFunctionOverload.Unary<T>	Helper interface for describing unary functions where the type-parameter is used to improve compile-time correctness of function bindings.
CelRuntime	The CelRuntime creates executable Program instances from CelAbstractSyntaxTree values.
CelRuntimeBuilder	Interface for building an instance of CelRuntime
CelRuntimeLibrary	CelCompilerLibrary defines the interface to extend functionalities beyond the CEL standard functions for CelRuntime.
CelVariableResolver	Functional interface that exposes a method to find a CEL variable value by name.
Dispatcher	An object which implements dispatching of function calls.
Dispatcher.ImmutableCopy	An Immutable copy of a Dispatcher.
GlobalResolver	An interface describing an object that can perform a lookup on a given name, returning the value associated with the so-named global variable.
IncompleteData	Deprecated.
Interpretable	Represent an expression which can be interpreted repeatedly using a given activation.
Interpreter	Interface to a CEL interpreter.
MessageFactory	Deprecated. Do not use.
MessageProvider	An object which allows to create and interpret messages.
Metadata	An interface which provides metadata for syntax nodes.
PartialMessageOrBuilder	Deprecated.
Registrar	An object which registers the functions that a Dispatcher calls.
Registrar.BinaryFunction<T1,T2>	Interface to a typed binary function without activation argument.
Registrar.Function	Interface to a general function.
Registrar.UnaryFunction<T>	Interface to a typed unary function without activation argument.
RuntimeTypeProvider	The RuntimeTypeProvider is a combination of the MessageProvider and TypeResolver interfaces.
TypeResolver	The TypeResolver determines the CEL type of Java-native values and assists with adapting check-time types to runtime values.
UnknownTrackingInterpretable	An interpretable that allows for tracking unknowns at runtime.

Class Summary

Class	Description
Activation	An object which allows to bind names to values.
CelAttribute	CelAttribute represents the select path from the root (.) to a single leaf value that may be derived from the activation (e.g.
CelAttribute.Qualifier	Representation of a single select qualifier or index.
CelAttributePattern	A Pattern for matching against CelAttributes.
CelRuntime.CelFunctionBinding	Binding consisting of an overload id, a Java-native argument signature, and an overload definition.
CelRuntime.Program	Creates an evaluable Program instance which is thread-safe and immutable.
CelRuntimeFactory	Helper class to construct new CelRuntime instances.
CelRuntimeLegacyImpl	CelRuntime implementation based on the legacy CEL-Java stack.
CelRuntimeLegacyImpl.Builder	Builder class for CelRuntimeLegacyImpl.
CelUnknownSet	Unknown set representation.
DefaultDispatcher	Default implementation of Dispatcher.
DefaultInterpreter	Default implementation of the CEL interpreter.
DefaultMetadata	Metadata implementation based on CheckedExpr.
DescriptorMessageProvider	An implementation of RuntimeTypeProvider which relies on proto descriptors.
DynamicMessageFactory	Deprecated. Do not use.
InterpreterException.Builder	Builder for InterpreterException.
InterpreterUtil	Util class for CEL interpreter.
MessageFactory.CombinedMessageFactory	The CombinedMessageFactory takes one or more MessageFactory instances and attempts to create a Message.Builder instance for a given messageName by calling each MessageFactory in the order that they are provided to the constructor.
PartialMessage	Deprecated.
RuntimeEquality	CEL Library Internals.
RuntimeHelpers	Helper methods for common CEL related routines.
RuntimeTypeProviderLegacyImpl	Bridge between the old RuntimeTypeProvider and CelValueProvider APIs.
RuntimeUnknownResolver	Runtime representation of the current state in an iterative evaluation session.
RuntimeUnknownResolver.Builder	Builder for RuntimeUnknownResolver.
StandardFunctions	Adds standard functions to a Registrar.
StandardTypeResolver	The StandardTypeResolver implements the TypeResolver and resolves types supported by the CEL standard environment.
UnknownContext	AsyncContext represents the state required for an iterative evaluation session in the CEL evaluator.
