Examples with DependencyAggregation com.facebook.buck.rules.DependencyAggregation used on opensource projects

Example 1 with DependencyAggregation

use of com.facebook.buck.rules.DependencyAggregation in project buck by facebook.

the class AbstractCxxSourceRuleFactory method requireAggregatedPreprocessDepsRule.

/**
   * Returns the no-op rule that aggregates the preprocessor dependencies.
   *
   * Individual compile rules can depend on it, instead of having to depend on every preprocessor
   * dep themselves. This turns O(n*m) dependencies into O(n+m) dependencies, where n is number of
   * files in a target, and m is the number of targets.
