Detailed Description

Additional functionality for class NSDate.

Category SCDate extends functionality of standard class NSDate.
This category was introduced in version 1.2.0.

Category declares the following properties:

• NSString* className - receiver's instance class name (read only)

Member Function Documentation

- (void) appendToFileStream:

(NSString *)

path

Appends the receiver's class instance to the new or existing stream file with the specified path.

Parameters:

path	- stream file path

Exceptions:

SCStreamException

- stream operation error detected

- (NSString *) className

Returns the receiver's instance class name.

Returns:

Class name

- (SCComparisonResult) compareWithObject:

(id<SCCollectionProtocol>)

object

Returns the result of comparison receiver's instance with the specified instance.

Parameters:

object

- second instance for comparison

Returns:

Result of comparison:

• SCComparisonEqual - instances are equal
• SCComparisonLess - the receiver's instance is less than second instance
• SCComparisonGreater - the receiver's instance is greater than second instance
• SCComparisonNotAllowed - instances cannot be compared

Exceptions:

SCCollectionException

- incompatible second instance detected

- (id< SCCollectionProtocol >) copyObject

Returns the copy of receiver's instance.

Returns:

Copy of receiver's instance

- (NSDictionary *) dataDictionary

Returns the dictionary with the receiver's data.

Returns:

Dictionary with the receiver's data

+ (NSDate *) dateWithCoder:

(NSCoder *)

coder

Parameters:

coder

- source coder

Returns:

A created class instance

+ (NSDate *) dateWithContentsOfSerializedFile:

(NSString *)

path

Parameters:

path	- source serialized file path

Returns:

A created class instance

+ (NSDate *) dateWithDataDictionary:

(NSDictionary *)

dictionary

Returns the class instance created by using the specified dictionary.

Parameters:

+ (NSDate *) dateWithFileStream:

(NSString *)

path

Returns the class instance created from the stream file with the specified path.

Parameters:

path	- stream file path

Returns:

A created class instance

Exceptions:

SCStreamException

- stream operation error detected

+ (NSDate *) dateWithStream:

(SCStream *)

stream

Returns the class instance created from the specified stream.

Parameters:

stream

- stream for reading class instance

Returns:

A created class instance

Exceptions:

SCStreamException	- stream operation error detected
SCSystemException	- system error detected

- (id) initWithContentsOfSerializedFile:

(NSString *)

path

Initializes the class instance using the contens of serialized file with the specified path.

Parameters:

path	- source serialized file path

Returns:

A newly initialized class instance

- (id) initWithDataDictionary:

(NSDictionary *)

dictionary

Initializes the class instance using the specified dictionary.

Parameters:

dictionary

- source dictionary

Returns:

A newly initialized class instance

- (id) initWithDataDictionaryFromFile:

(NSString *)

path

Initializes the class instance using the dictionary from the specified file.

Parameters:

path	- source dictionary file path

Returns:

A newly initialized class instance

- (id) initWithFileStream:

(NSString *)

path

Initializes class instance from the stream file with the specified path.

Parameters:

path	- stream file path

Returns:

A newly initialized class instance

Exceptions:

SCStreamException

- (id) initWithStream:

(SCStream *)

stream

Initializes the class instance from the specified stream.

Parameters:

stream

- stream for reading class instance

Returns:

A newly initialized class instance

Exceptions:

SCStreamException	- stream operation error detected
SCSystemException	- system error detected

- (BOOL) writeContentsToSerializedFile:

(NSString *)

path

Writes receiver's encoded data into the serialized file with the specified path.

Parameters:

path	- path at which to write the file

Returns:

YES if operation is successfully, otherwise NO

- (void) writeToDataDictionary:

(NSMutableDictionary *)

dictionary

Writes the receiver's data into the specified dictionary.

Parameters:

dictionary

- destination dictionary

- (void) writeToDataDictionaryFile:

(NSString *)

path

Atomically writes the receiver's data into the dictionary file with the specified path.

Parameters:

path	- path at which to write the file

- (void) writeToDataDictionaryFile:		(NSString *)	path
atomically:		(BOOL)	atomically

Writes the receiver's data into the dictionary file with the specified path.

Parameters:

path	- path at which to write the file
atomically	- YES for writing data to an auxiliary file, and then the auxiliary file is renamed to path, NO for writing data directly to path

- (void) writeToFileStream:

(NSString *)

path

stream

Saves the receiver's class instance to the specified stream.

Parameters:

stream

- stream for writing receiver's class instance

Exceptions:

SCStreamException	- stream operation error detected
SCSystemException	- system error detected
