Method Detail

• add

  boolean add(boolean element)

  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.

  Parameters:

  element - the value whose presence within me is to be ensured

  Returns:

  true iff I changed as a result of this call

  Throws:

  UnsupportedOperationException - when this operation is not supported

  IllegalArgumentException - may be thrown if some aspect of the specified element prevents it from being added to me

• addAll

  boolean addAll(BooleanCollection c)

  Adds all of the elements in the specified collection to me (optional operation).

  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

  Throws:

  UnsupportedOperationException - when this operation is not supported

  IllegalArgumentException - may be thrown if some aspect of some specified element prevents it from being added to me

• clear

  void clear()

  Removes all my elements (optional operation). I will be empty after this method successfully returns.

  Throws:

  UnsupportedOperationException - when this operation is not supported

• contains

  boolean contains(boolean element)

  Returns true iff I contain the specified element.

  Parameters:

  element - the value whose presence within me is to be tested

  Returns:

  true iff I contain the specified element

• containsAll

  boolean containsAll(BooleanCollection c)

  Returns true iff I contain all of the elements in the given collection.

  Parameters:

  c - the collection of elements whose presence within me is to be tested

  Returns:

  true iff I contain the all the specified elements

• isEmpty

  boolean isEmpty()

  Returns true iff I contain no elements.

  Returns:

  true iff I contain no elements.

• iterator

  BooleanIterator iterator()

  Returns an iterator over all my elements. This base interface places no constraints on the order in which the elements are returned by the returned iterator.

  Returns:

  an iterator over all my elements.

• removeAll

  boolean removeAll(BooleanCollection c)

  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.

  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

  Throws:

  UnsupportedOperationException - when this operation is not supported

• removeElement

  boolean removeElement(boolean element)

  Removes a single occurrence of the specified element (optional operation).

  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

  Throws:

  UnsupportedOperationException - when this operation is not supported

• retainAll

  boolean retainAll(BooleanCollection c)

  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.

  Parameters:

  c - the collection of elements to retain

  Returns:

  true iff I changed as a result of this call

  Throws:

  UnsupportedOperationException - when this operation is not supported

• size

  int size()

  Returns the number of elements I contain.

  Returns:

  the number of elements I contain

• toArray

  boolean[] toArray()

  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.

  Returns:

  an array containing all my elements

• toArray

  boolean[] toArray(boolean[] a)

  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.

  Parameters:

  a - an array that may be used to contain the elements

  Returns:

  an array containing all my elements
