Package dev.cel.compiler

Class CelCompilerImpl

java.lang.Object

dev.cel.compiler.CelCompilerImpl

All Implemented Interfaces:

CelChecker, EnvVisitable, CelCompiler, CelParser

@Immutable
@Internal
public final class CelCompilerImpl
extends java.lang.Object
implements CelCompiler, EnvVisitable

CelCompiler implementation which uses either the legacy or modernized CEL-Java stack to offer a stream-lined expression parse/type-check experience, via a single compile method.

CEL Library Internals. Do Not Use. Consumers should use factories, such as CelCompilerFactory instead to instantiate a compiler.

Method Detail

parse

public CelValidationResult parse(java.lang.String expression,
                                 java.lang.String description)

Description copied from interface: CelParser

Parse the input expression and return a CelValidationResult.

The description may be used to help tailor error messages for the location where the expression originates, e.g. a file name or form UI element.

Parse validates the syntax of an expression.

Specified by:

parse in interface CelParser

parse

public CelValidationResult parse(CelSource source)

Description copied from interface: CelParser

Parse the input expression and return a CelValidationResult.

The description may be used to help tailor error messages for the location where the expression originates, e.g. a file name or form UI element.

Parse validates the syntax of an expression.

Specified by:

parse in interface CelParser

check

public CelValidationResult check(CelAbstractSyntaxTree ast)

Description copied from interface: CelChecker

Check the input ast for type-agreement and return a CelValidationResult.

Check validates the type-agreement of the parsed CelAbstractSyntaxTree.

Specified by:

check in interface CelChecker

accept

public void accept(EnvVisitor envVisitor)

Specified by:

accept in interface EnvVisitable

newBuilder

public static CelCompilerBuilder newBuilder(CelParserBuilder parserBuilder,
                                            CelCheckerBuilder checkerBuilder)

Create a new builder for constructing a CelCompiler instance.

By default, CelOptions.DEFAULT are enabled, as is the CEL standard environment.
