Package dev.cel.common.values

Class ProtoCelValueConverter

java.lang.Object

dev.cel.common.values.ProtoCelValueConverter

@Immutable
@Internal
public final class ProtoCelValueConverter
extends java.lang.Object

CelValueConverter handles bidirectional conversion between native Java and protobuf objects to CelValue.

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.

newInstance

public static ProtoCelValueConverter newInstance(CelOptions celOptions,
                                                 CelDescriptorPool celDescriptorPool,
                                                 DynamicProto dynamicProto)

Constructs a new instance of ProtoCelValueConverter.

fromCelValueToJavaObject

public java.lang.Object fromCelValueToJavaObject(CelValue celValue)

Adapts a CelValue to a native Java object. The CelValue is adapted into protobuf object when an equivalent exists.

fromProtoMessageToCelValue

public CelValue fromProtoMessageToCelValue(com.google.protobuf.MessageOrBuilder message)

Adapts a Protobuf message into a CelValue.

fromJavaObjectToCelValue

public CelValue fromJavaObjectToCelValue(java.lang.Object value)

Adapts a plain old Java Object to a CelValue. Protobuf semantics take precedence for conversion.

fromProtoMessageFieldToCelValue

public CelValue fromProtoMessageFieldToCelValue(com.google.protobuf.Message message,
                                                com.google.protobuf.Descriptors.FieldDescriptor fieldDescriptor)

Adapts the protobuf message field into CelValue.

fromJavaPrimitiveToCelValue

protected CelValue fromJavaPrimitiveToCelValue(java.lang.Object value)

Adapts a plain old Java Object that are considered primitives to a CelValue.
