Package dev.cel.expr

Class Constant

  • All Implemented Interfaces:
    com.google.protobuf.Message, com.google.protobuf.MessageLite, com.google.protobuf.MessageLiteOrBuilder, com.google.protobuf.MessageOrBuilder, ConstantOrBuilder, java.io.Serializable
    public final class Constant
extends com.google.protobuf.GeneratedMessageV3
implements ConstantOrBuilder
     Represents a primitive literal.
 Named 'Constant' here for backwards compatibility.
 This is similar as the primitives supported in the well-known type
 `google.protobuf.Value`, but richer so it can represent CEL's full range of
 primitives.
 Lists and structs are not included as constants as these aggregate types may
 contain [Expr][cel.expr.Expr] elements which require evaluation and
 are thus not constant.
 Examples of constants include: `"hello"`, `b'bytes'`, `1u`, `4.2`, `-2`,
 `true`, `null`.
    Protobuf type cel.expr.Constant
