Method Details

bindingMultimapMerger

public static BiConsumer<Map<Key<?>,Set<Binding<?>>>,Map<Key<?>,Set<Binding<?>>>> bindingMultimapMerger()

next

public static <T> T[] next(T[] items,
 T item)

getScopeDisplayString

public static String getScopeDisplayString(Scope[] scope)

mergeMultibinders

public static void mergeMultibinders(Map<Key<?>,Multibinder<?>> into,
 Map<Key<?>,Multibinder<?>> from)

combineMultimap

public static <K,
V> void combineMultimap(Map<K,Set<V>> accumulator,
 Map<K,Set<V>> multimap)

override

public static <K,
V> Map<K,V> override(Map<K,V> into,
 Map<K,V> from)

toMultimap

public static <T,
K,
V> Collector<T,?,Map<K,Set<V>>> toMultimap(Function<? super T,? extends K> keyMapper,
 Function<? super T,? extends V> valueMapper)

squash

public static <K,
V> Map<K,V> squash(Map<K,Set<V>> multimap,
 BiFunction<K,Set<V>,V> squasher)

getLocation

public static String getLocation(@Nullable
 @Nullable Binding<?> binding)

printGraphVizGraph

public static void printGraphVizGraph(Trie<Scope,Map<Key<?>,Binding<?>>> trie)

A shortcut for printing the result of makeGraphVizGraph(io.activej.inject.util.Trie<io.activej.inject.Scope, java.util.Map<io.activej.inject.Key<?>, io.activej.inject.binding.Binding<?>>>) into the standard output.

makeGraphVizGraph

public static String makeGraphVizGraph(Trie<Scope,Map<Key<?>,Binding<?>>> trie)

Makes a GraphViz graph representation of the binding graph. Scopes are grouped nicely into subgraph boxes and dependencies are properly drawn from lower to upper scopes.

getKeyDisplayCenter

public static int getKeyDisplayCenter(Key<?> key)

getDisplayString

public static String getDisplayString(Class<? extends Annotation> annotationType,
 @Nullable
 @Nullable Annotation annotation)

getDisplayString

public static String getDisplayString(Object object)

drawCycle

public static String drawCycle(Key<?>[] cycle)

isMarker

public static boolean isMarker(Class<? extends Annotation> annotationType)

sortPatternsMap

public static <T>
LinkedHashMap<KeyPattern<?>,Set<T>> sortPatternsMap(Map<KeyPattern<?>,Set<T>> map)
