Example 8 with BuildConfiguration

use of com.google.devtools.build.lib.analysis.config.BuildConfiguration in project bazel by bazelbuild.

the class DependencyResolver method resolveLateBoundAttributes.

/**
   * Resolves the dependencies for all late-bound attributes in this rule.
   *
   * <p>Late-bound attributes need special handling because they require configuration
   * transitions to determine their values.
   *
   * <p>In other words, the normal process of dependency resolution is:
   * <ol>
   *   <li>Find every label value in the rule's attributes</li>
   *   <li>Apply configuration transitions over each value to get its dep configuration
   *   <li>Return each value with its dep configuration</li>
   * </ol>
   *
   * This doesn't work for late-bound attributes because you can't get their values without
   * knowing the configuration first. And that configuration may not be the owning rule's
   * configuration. Specifically, {@link LateBoundDefault#useHostConfiguration()} switches to the
   * host config and late-bound split attributes branch into multiple split configs.
   *
   * <p>This method implements that logic and makes sure the normal configuration
   * transition logic mixes with it cleanly.
   *
   * @param depResolver the resolver for this rule's deps
   * @param ruleConfig the rule's configuration
   * @param hostConfig the equivalent host configuration
