| Method Summary |
|
| public boolean | add(Object object)
Adds a new element to the bag, incrementing its count in the underlying map. |
| public boolean | add(Object object, int nCopies)
Adds a new element to the bag, incrementing its count in the map. |
| public boolean | addAll(Collection coll)
Invokes
AbstractMapBag.add(Object) for each element in the given collection. |
| public void | clear()
Clears the bag by clearing the underlying map. |
| public boolean | contains(Object object)
Determines if the bag contains the given element by checking if the
underlying map contains the element as a key. |
| public boolean | containsAll(Collection coll)
Determines if the bag contains the given elements. |
| boolean | containsAll(Bag other)
Returns true if the bag contains all elements in
the given collection, respecting cardinality. |
| protected void | doReadObject(Map map, ObjectInputStream in)
Read the map in using a custom routine. |
| protected void | doWriteObject(ObjectOutputStream out)
Write the map out using a custom routine. |
| public boolean | equals(Object object)
Compares this Bag to another. |
| public int | getCount(Object object)
Returns the number of occurrence of the given element in this bag
by looking up its count in the underlying map. |
| protected Map | getMap()
Utility method for implementations to access the map that backs
this bag. |
| public int | hashCode()
Gets a hash code for the Bag compatible with the definition of equals. |
| public boolean | isEmpty()
Returns true if the underlying map is empty. |
| public Iterator | iterator()
Gets an iterator over the bag elements. |
| public boolean | remove(Object object)
Removes all copies of the specified object from the bag. |
| public boolean | remove(Object object, int nCopies)
Removes a specified number of copies of an object from the bag. |
| public boolean | removeAll(Collection coll)
Removes objects from the bag according to their count in the specified collection. |
| public boolean | retainAll(Collection coll)
Remove any members of the bag that are not in the given
bag, respecting cardinality. |
| boolean | retainAll(Bag other)
Remove any members of the bag that are not in the given
bag, respecting cardinality. |
| public int | size()
Returns the number of elements in this bag. |
| public Object[] | toArray()
Returns an array of all of this bag's elements. |
| public Object[] | toArray(Object[] array)
Returns an array of all of this bag's elements. |
| public String | toString()
