Interface CxxLibraryDescription.TransitiveCxxPreprocessorInputFunction

Enclosing class:

CxxLibraryDescription

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public static interface CxxLibraryDescription.TransitiveCxxPreprocessorInputFunction

This is a hack to allow fine grained control over how the transitive CxxPreprocessorInputs are found. Since not all Descriptions which use CxxLibraryDescription generate a CxxLibrary, blinding attempting to require it will not work.

Therefore for those other rules, we create the list from scratch.

Method Summary

Modifier and Type	Method and Description
java.util.stream.Stream<CxxPreprocessorInput>	apply(BuildTarget target, ActionGraphBuilder graphBuilder, CxxPlatform cxxPlatform, com.google.common.collect.ImmutableSet<BuildRule> deps, CxxDeps privateDeps)
static CxxLibraryDescription.TransitiveCxxPreprocessorInputFunction	fromDeps() Retrieve the transitive CxxPreprocessorInput from an explicitly specified deps list.
static CxxLibraryDescription.TransitiveCxxPreprocessorInputFunction	fromLibraryRule() Retrieve the transitive CxxPreprocessorInput from the CxxLibrary rule.

Method Detail

apply

java.util.stream.Stream<CxxPreprocessorInput> apply(BuildTarget target,
                                                    ActionGraphBuilder graphBuilder,
                                                    CxxPlatform cxxPlatform,
                                                    com.google.common.collect.ImmutableSet<BuildRule> deps,
                                                    CxxDeps privateDeps)

fromLibraryRule

static CxxLibraryDescription.TransitiveCxxPreprocessorInputFunction fromLibraryRule()

Retrieve the transitive CxxPreprocessorInput from the CxxLibrary rule.

This is used by CxxLibrary and AppleLibrary. Rules that do not generate a CxxLibrary rule (namely AppleTest) cannot use this.

fromDeps

static CxxLibraryDescription.TransitiveCxxPreprocessorInputFunction fromDeps()

Retrieve the transitive CxxPreprocessorInput from an explicitly specified deps list.

This is used by AppleTest, which doesn't generate a CxxLibrary rule that computes this.
