Example 1 with TransitiveTargetValue

use of com.google.devtools.build.lib.skyframe.TransitiveTargetValue in project bazel by bazelbuild.

the class GenQuery method constructPackageMap.

   * Precomputes the transitive closure of the scope. Returns two maps: one identifying the
   * successful packages, and the other identifying the valid targets. Breaks in the transitive
   * closure of the scope will cause the query to error out early.
