Method Detail

• sizeSupplier

  public static com.google.common.base.Supplier<java.lang.Integer> sizeSupplier(java.lang.Iterable<?> collection)

• sizeFunction

  public static com.google.common.base.Function<java.lang.Iterable<?>,java.lang.Integer> sizeFunction()

• sizeFunction

  public static com.google.common.base.Function<java.lang.Iterable<?>,java.lang.Integer> sizeFunction(java.lang.Integer valueIfInputNull)

• keys

  public static <K> com.google.common.base.Function<java.util.Map<K,?>,java.util.Set<K>> keys()

• mapSize

  public static <K> com.google.common.base.Function<java.util.Map<K,?>,java.lang.Integer> mapSize()

• mapSize

  public static <K> com.google.common.base.Function<java.util.Map<K,?>,java.lang.Integer> mapSize(java.lang.Integer valueIfNull)

• equalsSetOf

  public static com.google.common.base.Predicate<java.lang.Iterable<?>> equalsSetOf(java.lang.Object... target)

  default guava Equals predicate will reflect order of target, and will fail when matching against a list; this treats them both as sets

• equalsSet

  public static com.google.common.base.Predicate<java.lang.Iterable<?>> equalsSet(java.lang.Iterable<?> target)

• sizeEquals

  public static com.google.common.base.Predicate<java.lang.Iterable<?>> sizeEquals(int targetSize)

• mapSizeEquals

  public static <K> com.google.common.base.Predicate<java.util.Map<K,?>> mapSizeEquals(int targetSize)

• limit

  public static <T,I extends java.lang.Iterable<T>> com.google.common.base.Function<I,java.util.List<T>> limit(int max)

• contains

  public static <I,T extends java.util.Collection<I>> com.google.common.base.Predicate<T> contains(I item)

• all

  public static <T,TT extends java.lang.Iterable<T>> com.google.common.base.Predicate<TT> all(com.google.common.base.Predicate<T> attributeSatisfies)

• quorum

  public static <T,TT extends java.lang.Iterable<T>> com.google.common.base.Predicate<TT> quorum(QuorumCheck quorumCheck,
                                                                                 com.google.common.base.Predicate<T> attributeSatisfies)
