| Defined Types
NSComparisonResult DECLARED IN foundation/NSObject.h |
| SYNOPSIS typedef enum _NSComparisonResult { |
NSOrderedAscending =  1,NSOrderedSame,NSOrderedDescending} NSComparisonResult |
| DESCRIPTION An NSComparisonResult indicates how items in a request are ordered, from the first one given in a method invocation or function call to the last (that is, left-to-right in code).
NSRange DECLARED IN foundation/NSRange.h |
| SYNOPSIS typedef struct _NSRange { |
| unsigned int location;unsigned int length; } NSRange |
| DESCRIPTION An NSRange describes a portion of a series--such as characters in a string or objects in an NSArray. Its location member gives the start index (0 is the first, as in C arrays), and its length member gives the number of items in the range (and can be zero).
NSStringEncoding DECLARED IN foundation/NSString.h |
| SYNOPSIS typedef enum _NSStringEncoding { |
| NSUnicodeStringEncoding = 0,NSASCIIStringEncoding,NSNEXTSTEPStringEncoding,NSEUCStringEncoding,NSUTFStringEncoding,NSISOLatin1StringEncoding,NSSymbolStringEncoding,NSNonLossyASCIIStringEncoding } NSStringEncoding |
| DESCRIPTION These values represent the various character encodings supported by the NSString classes. These encodings are documented more fully elsewhere; here are some short descriptions: |
| Encoding | Description | |
| NSASCIIStringEncoding | Strict 7-bit ASCII encoding within 8-bit chars | |
| NSEUCStringEncoding | 8-bit EUC encoding for Japanese text | |
| NSISOLatin1StringEncoding | 8-bit ISO Latin 1 encoding | |
| NSNEXTSTEPStringEncoding | 8-bit ASCII encoding with NEXTSTEP extensions (see Appendix C of the NEXTSTEP General Reference) |
| NSNonLossyASCIIStringEncoding |
| <<forthcoming>> |
| NSSymbolStringEncoding | <<forthcoming>> |
| NSUnicodeStringEncoding | The canonical Unicode encoding for string objects | |
| NSUTFStringEncoding | An 8-bit representation of Unicode characters, suitable for transmission or storage by ASCII-based systems <<should we document this format?>> |
| Symbolic Constants
NSHashStringLength DECLARED IN foundation/NSString.h |
| SYNOPSIS NSHashStringLength |
| NSMaximumStringLength
DECLARED IN foundation/NSString.h |
| SYNOPSIS NSMaximumStringLength |
| DESCRIPTION NSMaximumStringLength is the greatest possible length for an NSString.
NSNotFound DECLARED IN foundation/NSObject.h |
| SYNOPSIS NSNotFound |
| DESCRIPTION A method or function return value of NSNotFound indicates that the item requested couldn't be found or doesn't exist. It's typically used by various methods and functions that search for items in serial data and return indices, such as characters in a string object or ids in an NSArray.
Enumerations
NSStringSearchFlags DECLARED IN foundation/NSString.h |
| SYNOPSIS enum { |
| NSCaseInsensitiveSearch = 1;NSLiteralSearch = 2;NSBackwardsSearch = 4;NSAnchoredSearch = 8; }; |
| DESCRIPTION These values represent the options available to many of the string classes' searching and comparison methods. See the NSString class cluster description for details on the effects of these options. |
