Package dev.cel.common.values

Class ProtoCelValueConverter

  • @Immutable
@Internal
public final class ProtoCelValueConverter
extends BaseProtoCelValueConverter
    ProtoCelValueConverter handles bidirectional conversion between native Java and protobuf objects to CelValue. This converter leverages descriptors, thus requires the full version of protobuf implementation.

    Protobuf semantics take precedence for conversion. For example, CEL's TimestampValue will be converted into Protobuf's Timestamp instead of java.time.Instant.

    CEL Library Internals. Do Not Use.
