- Constructor Detail

```
public CollectionBooleanCollection(Collection collection)
```
    Creates an BooleanCollection wrapping the specified Collection.
    
    See Also:
    wrap(java.util.Collection)
- Method Detail
  - wrap
```
public static BooleanCollection wrap(Collection collection)
```
    Create an BooleanCollection wrapping the specified Collection. When the given collection is null, returns null.
    
    Parameters:
    collection - the (possibly null) Collection to wrap
    
    Returns:
    an BooleanCollection wrapping the given collection, or null when collection is null.
  - getCollection
```
protected Collection getCollection()
```
  - add
```
public boolean add(boolean element)
```
    Description copied from interface: BooleanCollection
    
    Ensures that I contain the specified element (optional operation). Returns true iff I changed as a result of this call.
    If a collection refuses to add the specified element for any reason other than that it already contains the element, it must throw an exception (rather than simply returning false). This preserves the invariant that a collection always contains the specified element after this call returns.
    
    Specified by:
    
    add in interface BooleanCollection
    
    Parameters:
    element - the value whose presence within me is to be ensured
    
    Returns:
    true iff I changed as a result of this call
  - addAll
```
public boolean addAll(BooleanCollection c)
```
    Description copied from interface: BooleanCollection
    
    Adds all of the elements in the specified collection to me (optional operation).
    
    Specified by:
    
    addAll in interface BooleanCollection
    
    Parameters:
    c - the collection of elements whose presence within me is to be ensured
    
    Returns:
    true iff I changed as a result of this call
  - clear
```
public void clear()
```
    Description copied from interface: BooleanCollection
    
    Removes all my elements (optional operation). I will be empty after this method successfully returns.
    
    Specified by:
    
    clear in interface BooleanCollection
  - contains
```
public boolean contains(boolean element)
```
    Description copied from interface: BooleanCollection
    
    Returns true iff I contain the specified element.
    
    Specified by:
    
    contains in interface BooleanCollection
    
    Parameters:
    element - the value whose presence within me is to be tested
    
    Returns:
    true iff I contain the specified element
  - containsAll
```
public boolean containsAll(BooleanCollection c)
```
    Description copied from interface: BooleanCollection
    
    Returns true iff I contain all of the elements in the given collection.
    
    Specified by:
    
    containsAll in interface BooleanCollection
    
    Parameters:
    c - the collection of elements whose presence within me is to be tested
    
    Returns:
    true iff I contain the all the specified elements
  - toString
```
public String toString()
```
    Overrides:
    
    toString in class Object
  - isEmpty
```
public boolean isEmpty()
```
    Description copied from interface: BooleanCollection
    
    Returns true iff I contain no elements.
    
    Specified by:
    
    isEmpty in interface BooleanCollection
    
    Returns:
    true iff I contain no elements.
  - iterator
```
public BooleanIterator iterator()
```
    wraps the Iterator returned by my underlying Collection, if any.
    
    Specified by:
    
    iterator in interface BooleanCollection
    
    Returns:
    an iterator over all my elements.
  - removeElement
```
public boolean removeElement(boolean element)
```
    Description copied from interface: BooleanCollection
    
    Removes a single occurrence of the specified element (optional operation).
    
    Specified by:
    
    removeElement in interface BooleanCollection
    
    Parameters:
    element - the element to remove, if present
    
    Returns:
    true iff I contained the specified element, in other words, iff I changed as a result of this call
  - removeAll
```
public boolean removeAll(BooleanCollection c)
```
    Description copied from interface: BooleanCollection
    
    Removes all of my elements that are contained in the specified collection (optional operation). The behavior of this method is unspecified if the given collection is modified while this method is executing. Note that this includes the case in which the given collection is this collection, and it is not empty.
    
    Specified by:
    
    removeAll in interface BooleanCollection
    
    Parameters:
    c - the collection of elements to remove
    
    Returns:
    true iff I contained the at least one of the specified elements, in other words, returns true iff I changed as a result of this call
  - retainAll
```
public boolean retainAll(BooleanCollection c)
```
    Description copied from interface: BooleanCollection
    
    Removes all of my elements that are not contained in the specified collection (optional operation). (In other words, retains only my elements that are contained in the specified collection.) The behavior of this method is unspecified if the given collection is modified while this method is executing.
    
    Specified by:
    
    retainAll in interface BooleanCollection
    
    Parameters:
    c - the collection of elements to retain
    
    Returns:
    true iff I changed as a result of this call
  - size
```
public int size()
```
    Description copied from interface: BooleanCollection
    
    Returns the number of elements I contain.
    
    Specified by:
    
    size in interface BooleanCollection
    
    Returns:
    the number of elements I contain
  - toArray
```
public boolean[] toArray()
```
    Description copied from interface: BooleanCollection
    
    Returns an array containing all of my elements. The length of the returned array will be equal to my size.
    The returned array will be independent of me, so that callers may modify that returned array without modifying this collection.
    When I guarantee the order in which elements are returned by an iterator, the returned array will contain elements in the same order.
    
    Specified by:
    
    toArray in interface BooleanCollection
    
    Returns:
    an array containing all my elements
  - toArray
```
public boolean[] toArray(boolean[] dest)
```
    Description copied from interface: BooleanCollection
    
    Returns an array containing all of my elements, using the given array if it is large enough. When the length of the given array is larger than the number of elements I contain, values outside of my range will be unchanged.
    The returned array will be independent of me, so that callers may modify that returned array without modifying this collection.
    When I guarantee the order in which elements are returned by an iterator, the returned array will contain elements in the same order.
    
    Specified by:
    
    toArray in interface BooleanCollection
    
    Parameters:
    dest - an array that may be used to contain the elements
    
    Returns:
    an array containing all my elements
