ManagedBuffer

A class whose instances contain a property of type Header and raw storage for an array of Element, whose size is determined at instance creation.

class ManagedBuffer<Header, Element>

Overview

Note that the Element array is suitably-aligned raw memory. You are expected to construct and—if necessary—destroy objects there yourself, using the APIs on UnsafeMutablePointer<Element>. Typical usage stores a count and capacity in Header and destroys any live elements in the deinit of a subclass.

Members

Instance Properties

var capacity: Int
The actual number of elements that can be stored in this object.
var header: Header
The stored Header instance.

Type Methods

class func create(minimumCapacity: Int, makingHeaderWith: (ManagedBuffer<Header, Element>) throws -> Header) rethrows -> ManagedBuffer<Header, Element>
Create a new instance of the most-derived class, calling factory on the partially-constructed object to generate an initial Header.

Instance Methods

func withUnsafeMutablePointerToElements<R>((UnsafeMutablePointer<Element>) throws -> R) rethrows -> R
Call body with an UnsafeMutablePointer to the Element storage.
func withUnsafeMutablePointerToHeader<R>((UnsafeMutablePointer<Header>) throws -> R) rethrows -> R
Call body with an UnsafeMutablePointer to the stored Header.
func withUnsafeMutablePointers<R>((UnsafeMutablePointer<Header>, UnsafeMutablePointer<Element>) throws -> R) rethrows -> R
Call body with UnsafeMutablePointers to the stored Header and raw Element storage.
