Example 1 with Descriptor

use of com.google.devtools.build.lib.rules.SkylarkAttr.Descriptor in project bazel by bazelbuild.

the class SkylarkRuleClassFunctionsTest method buildAttribute.

private Attribute buildAttribute(String name, String... lines) throws Exception {
    String[] strings = lines.clone();
    strings[strings.length - 1] = String.format("%s = %s", name, strings[strings.length - 1]);
    evalAndExport(strings);
    Descriptor lookup = (Descriptor) ev.lookup(name);
    return lookup != null ? lookup.build(name) : null;
}

Example 2 with Descriptor
