Example 4 with Qualifier

use of org.projectnessie.cel.interpreter.AttributeFactory.Qualifier in project cel-java by projectnessie.

the class AttributesTest method attributesRelativeAttr_OneOf.

    // }
    // 
    // The expression being evaluated is: <map-literal>.a[-1][b] -> 42
    // 
    // However, since the test is validating what happens with maybe attributes
    // the attribute resolution must also consider the following variations:
    // - <map-literal>.a[-1][acme.ns.b]

    // The correct behavior should yield the value of the last alternative.
