Source Link

Document

Creates an index ImmutableListMultimap that contains the results of applying a specified function to each item in an Iterator of values.

Usage

From source file:dagger.internal.codegen.SubcomponentNames.java

private static ImmutableMap<ComponentDescriptor, String> namesByDescriptor(BindingGraph graph) {
    ImmutableListMultimap<String, ComponentDescriptor> componentDescriptorsBySimpleName = Multimaps.index(
            graph.componentDescriptors(),
            componentDescriptor -> componentDescriptor.typeElement().getSimpleName().toString());
    ImmutableMap<ComponentDescriptor, Namer> componentNamers = qualifiedNames(graph.componentDescriptors());
    Map<ComponentDescriptor, String> subcomponentImplSimpleNames = new LinkedHashMap<>();
    componentDescriptorsBySimpleName.asMap().values().forEach(components -> subcomponentImplSimpleNames
            .putAll(disambiguateConflictingSimpleNames(components, componentNamers)));
    subcomponentImplSimpleNames.remove(graph.componentDescriptor());
