public static DoubleCollection wrap(java.util.Collection collection)
DoubleCollection wrapping
the specified Collection. When
the given collection is null,
returns null.

DoubleCollection wrapping the given
collection, or null when collection is
null.protected java.util.Collection getCollection()
getCollection in class AbstractCollectionDoubleCollectionpublic boolean add(double element)
DoubleCollectiontrue
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.

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

DoubleCollectionempty after this

removeAll in interface DoubleCollectionc - the collection of elements to remove
true iff I contained the at least one of the
specified elements, in other words, returns true

DoubleCollectionsize.
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.

same order.
