Method Detail

newHashMapFrom

public static <K,V> java.util.Map<K,V> newHashMapFrom(java.lang.Iterable<? extends V> source,
                                                      com.google.common.base.Function<V,Pair<K,V>> function)

putAll

public static <K,V> void putAll(java.util.Map<K,? super V> map,
                                java.lang.Iterable<Pair<K,V>> iterable)

mutableUniqueIndex

public static <K,V> java.util.Map<K,V> mutableUniqueIndex(java.lang.Iterable<? extends V> values,
                                                          com.google.common.base.Function<? super V,? extends K> indexGenerator)

mutableLinkedUniqueIndex

public static <K,V> java.util.LinkedHashMap<K,V> mutableLinkedUniqueIndex(java.lang.Iterable<? extends V> values,
                                                                          com.google.common.base.Function<? super V,? extends K> indexGenerator)

populateMap

public static <K,V> V populateMap(@NotNull
                                  java.util.Map<K,V> map,
                                  @NotNull
                                  V input,
                                  @NotNull
                                  com.google.common.base.Function<? super V,? extends K> indexGenerator)

Add entry to the map using Function to generate a key

Parameters:

map - map that will get an extra element

input - element to be added to map

indexGenerator - function that will generate key for a given element

Returns:

same behavior as Map.put(Object, Object)

newNullAwareCache

@NotNull
public static <K,V> NullAwareCache<K,V> newNullAwareCache(com.google.common.cache.CacheBuilder<java.lang.Object,java.lang.Object> builder,
                                                                  com.google.common.cache.CacheLoader<? super K,? extends V> loader)
