Class BidiConverter<A,B>

java.lang.Object

dev.cel.common.internal.BidiConverter<A,B>

Type Parameters:

A - The proto value type.

B - The CEL value type.

@CheckReturnValue
@Internal
public abstract class BidiConverter<A,B>
extends java.lang.Object

The BidiConverter is a bidirectional converter which contains Converter objects to forward convert from proto to CEL and backward convert from CEL to proto.

Use the BidiConverter when dealing with reading and constructing proto messages during expression interpretation as CEL numeric primitives are wider than many of the proto primitives.

CEL Library Internals. Do Not Use.
