Example 6 with PackageGroup

use of com.google.devtools.build.lib.packages.PackageGroup in project bazel by bazelbuild.

the class DependencyResolver method dependentNodeMap.

/**
   * Returns ids for dependent nodes of a given node, sorted by attribute. Note that some
   * dependencies do not have a corresponding attribute here, and we use the null attribute to
   * represent those edges.
   *
   * <p>If {@code aspects} is empty, returns the dependent nodes of the configured target node
   * representing the given target and configuration.
   *
   * Otherwise {@code aspects} represents an aspect path. The function returns dependent nodes
   * of the entire path applied to given target and configuration. These are the depenent nodes
   * of the last aspect in the path.
   *
   * <p>This also implements the first step of applying
   * configuration transitions, namely, split transitions. This needs to be done before the labels
   * are resolved because late bound attributes depend on the configuration. A good example for this
   * is @{code :cc_toolchain}.
   *
   * <p>The long-term goal is that most configuration transitions be applied here. However, in order
   * to do that, we first have to eliminate transitions that depend on the rule class of the
   * dependency.
   *
   * @param node the target/configuration being evaluated
   * @param hostConfig the configuration this target would use if it was evaluated as a host tool.
   *     This is needed to support {@link LateBoundDefault#useHostConfiguration()}.
   * @param aspects the aspects applied to this target (if any)
   * @param configConditions resolver for config_setting labels
   * @param rootCauses collector for dep labels that can't be (loading phase) loaded
   * @return a mapping of each attribute in this rule or aspects to its dependent nodes
