Example 1 with AbstractBottomUpTraversal

use of com.facebook.buck.graph.AbstractBottomUpTraversal in project buck by facebook.

the class ProjectGeneratorTest method getBuildRuleResolverNodeFunction.

private Function<TargetNode<?, ?>, BuildRuleResolver> getBuildRuleResolverNodeFunction(final TargetGraph targetGraph) {
    BuildRuleResolver resolver = new BuildRuleResolver(targetGraph, new DefaultTargetNodeToBuildRuleTransformer());
    AbstractBottomUpTraversal<TargetNode<?, ?>, RuntimeException> bottomUpTraversal = new AbstractBottomUpTraversal<TargetNode<?, ?>, RuntimeException>(targetGraph) {

        @Override
        @SuppressWarnings("PMD.EmptyCatchBlock")
        public void visit(TargetNode<?, ?> node) {
            try {
                resolver.requireRule(node.getBuildTarget());
            } catch (Exception e) {
            // NOTE(agallagher): A large number of the tests appear to setup their target nodes
            // incorrectly, causing action graph creation to fail with lots of missing expected
            // Apple C/C++ platform flavors.  This is gross, but to support tests that need a
            // complete sub-action graph, just skip over the errors.
            }
        }
    };
    bottomUpTraversal.traverse();
    return input -> resolver;
}

Example 2 with AbstractBottomUpTraversal

use of com.facebook.buck.graph.AbstractBottomUpTraversal in project buck by facebook.

the class ActionGraphCache method createActionGraph.

    final BuildRuleResolver resolver = new BuildRuleResolver(targetGraph, transformer, eventBus);
    AbstractBottomUpTraversal<TargetNode<?, ?>, RuntimeException> bottomUpTraversal = new AbstractBottomUpTraversal<TargetNode<?, ?>, RuntimeException>(targetGraph) {

        @Override
        public void visit(TargetNode<?, ?> node) {
            try {
                resolver.requireRule(node.getBuildTarget());
            } catch (NoSuchBuildTargetException e) {
                throw new HumanReadableException(e);
            }
