Software documentation for the NSURLRequest class

NSURLRequest : NSObject

Declared in:
Foundation/NSURLRequest.h
Conforms to:
NSCoding
NSCopying
NSMutableCopying
Availability: MacOS-X 10.2.0, Base 1.13.0

This class encapsulates information about a request to load a URL, how to cache the results, and when to deal with a slow/hung load process by timing out.
Instance Variables

Method summary

requestWithURL: 

+ (id) requestWithURL: (NSURL*)URL;
Availability: MacOS-X 10.2.0, Base 1.13.0

Description forthcoming.

requestWithURL: cachePolicy: timeoutInterval: 

+ (id) requestWithURL: (NSURL*)URL cachePolicy: (NSURLRequestCachePolicy)cachePolicy timeoutInterval: (NSTimeInterval)timeoutInterval;
Availability: MacOS-X 10.2.0, Base 1.13.0

Returns an autoreleased instance initialised with the specified URL, cachePolicy, and timeoutInterval.

URL 

- (NSURL*) URL;
Availability: MacOS-X 10.2.0, Base 1.13.0

Returns the URL associated with the receiver.

cachePolicy 

- (NSURLRequestCachePolicy) cachePolicy;
Availability: MacOS-X 10.2.0, Base 1.13.0

Returns the cache policy associated with the receiver.

initWithURL: 

- (id) initWithURL: (NSURL*)URL;
Availability: MacOS-X 10.2.0, Base 1.13.0

Initialises the reveiver with the specified URL and with the default cache policy (NSURLRequestUseProtocolCachePolicy) and a sixty second timeout.

initWithURL: cachePolicy: timeoutInterval: 

- (id) initWithURL: (NSURL*)URL cachePolicy: (NSURLRequestCachePolicy)cachePolicy timeoutInterval: (NSTimeInterval)timeoutInterval;
Availability: MacOS-X 10.2.0, Base 1.13.0

Initialises the receiver with the specified URL, cachePolicy, and timeoutInterval.

mainDocumentURL 

- (NSURL*) mainDocumentURL;
Availability: MacOS-X 10.2.0, Base 1.13.0

Returns the main document URL for the receiver.
Currently unused.
This is intended for use with frames and similar situations where a main document has a large number of subsidiary documents.

timeoutInterval 

- (NSTimeInterval) timeoutInterval;
Availability: MacOS-X 10.2.0, Base 1.13.0

Returns the timeout interval associated with the receiver.
This is a value in seconds specifying how long the load process may be inactive (waiting for data to arrive from the server) before the load is mconsidered to have failed due to a timeout.

Instance Variables for NSURLRequest Class

_NSURLRequestInternal

@protected void* _NSURLRequestInternal;
Availability: MacOS-X 10.2.0, Base 1.13.0

Warning the underscore at the start of the name of this instance variable indicates that, even though it is not technically private, it is intended for internal use within the package, and you should not use the variable in other code.
