init(bufferClass: AnyClass, minimumCapacity: Int, makingHeaderWith factory: (AnyObject, (AnyObject) -> Int) throws -> Header) rethrows Create with new storage containing an initial Header and space for at least minimumCapacity elements.
init(unsafeBufferObject buffer: AnyObject) Manage the given buffer.
var buffer: AnyObject { get }Returns the object instance being used for storage.
var capacity: Int { get }The actual number of elements that can be stored in this object.
var header: Header { get set }The stored Header instance.
static func == (lhs: ManagedBufferPointer<Header, Element>, rhs: ManagedBufferPointer<Header, Element>) -> Bool mutating func isUniqueReference() -> Bool Returns true if self holds the only strong reference to its buffer; otherwise, returns false.
