| Constructor | Description |
|---|---|
AbstractHashBag() |
| Modifier and Type | Method | Description |
|---|---|---|
boolean |
add(T item) |
|
int |
addOccurrences(T item,
int occurrences) |
Add number of
occurrences for an item. |
void |
clear() |
|
boolean |
contains(Object o) |
Returns true if the iterable has an element which responds true to element.equals(object).
|
void |
each(Procedure<? super T> procedure) |
The procedure is executed for each element in the iterable.
|
boolean |
equals(Object other) |
Two bags
b1 and b2 are equal if m1.toMapOfItemToCount().equals(m2.toMapOfItemToCount()). |
<P> void |
forEachWith(Procedure2<? super T,? super P> procedure,
P parameter) |
The procedure2 is evaluated for each element in the iterable with the specified parameter provided
as the second argument.
|
void |
forEachWithIndex(ObjectIntProcedure<? super T> objectIntProcedure) |
Iterates over the iterable passing each element and the current relative int index to the specified instance of
ObjectIntProcedure.
|
void |
forEachWithOccurrences(ObjectIntProcedure<? super T> objectIntProcedure) |
For each distinct item, with the number of occurrences, execute the specified procedure.
|
<V> HashBagMultimap<V,T> |
groupBy(Function<? super T,? extends V> function) |
For each element of the iterable, the function is evaluated and the results of these evaluations are collected
into a new multimap, where the transformed value is the key and the original values are added to the same (or similar)
species of collection as the source iterable.
|
<V> HashBagMultimap<V,T> |
groupByEach(Function<? super T,? extends Iterable<V>> function) |
Similar to
RichIterable.groupBy(Function), except the result of evaluating function will return a collection of keys
for each value. |
int |
hashCode() |
Returns the hash code for this Bag, defined as this.
Bag.toMapOfItemToCount().hashCode(). |
boolean |
isEmpty() |
Returns true if this iterable has zero items.
|
Iterator<T> |
iterator() |
|
int |
occurrencesOf(Object item) |
The occurrences of a distinct item in the bag.
|
boolean |
remove(Object item) |
|
boolean |
removeAllIterable(Iterable<?> iterable) |
|
boolean |
removeIf(Predicate<? super T> predicate) |
Removes all elements in the collection that evaluate to true for the specified predicate.
|
<P> boolean |
removeIfWith(Predicate2<? super T,? super P> predicate,
P parameter) |
Removes all elements in the collection that evaluate to true for the specified predicate2 and parameter.
|
boolean |
removeOccurrences(Object item,
int occurrences) |
|
boolean |
setOccurrences(T item,
int occurrences) |
|
int |
size() |
Returns the number of items in this iterable.
|
int |
sizeDistinct() |
The size of the Bag when counting only distinct elements.
|
MutableMap<T,Integer> |
toMapOfItemToCount() |
Converts the Bag to a Map of the Item type to its count as an Integer.

MutableBagIterableoccurrences for an item. If the item does not exist, then the item is added to the bag.
For Example:
MutableBagIterable<String> names = Bags.mutable.of("A", "B", "B");
Assert.assertEquals(4, names.addOccurrences("A", 3));

RichIterableExample using a Java 8 lambda expression:
people.each(person -> LOGGER.info(person.getName()));
Example using an anonymous inner class:
people.each(new Procedure<Person>()
{
public void value(Person person)
{
LOGGER.info(person.getName());
}
});
This method is a variant of InternalIterable.forEach(Procedure)
that has a signature conflict with Iterable.forEach(java.util.function.Consumer).public void forEachWithIndex(ObjectIntProcedure<? super T> objectIntProcedure)
InternalIterableExample using a Java 8 lambda:
people.forEachWithIndex((Person person, int index) -> LOGGER.info("Index: " + index + " person: " + person.getName()));
Example using an anonymous inner class:
people.forEachWithIndex(new ObjectIntProcedure<Person>()
{
public void value(Person person, int index)
{
LOGGER.info("Index: " + index + " person: " + person.getName());
}
