Inherits from NSObject
Declared in DTASN1Parser.h

Overview

Instances of this class parse ASN1 documents in an event-driven manner. A DTASN1Parser notifies its delegate about the items (elements, collections, and so on) that it encounters as it processes an ASN1 document. It does not itself do anything with those parsed items except report them. It also reports parsing errors. For convenience, a DTASN1Parser object in the following descriptions is sometimes referred to as a parser object.

Tasks

Initializing a Parser Object

Parsing

Properties

delegate

An object that is the parsing delegate. It is not retained. The delegate must conform to the DTASN1ParserDelegate Protocol protocol.

@property (nonatomic, DT_WEAK_PROPERTY) id<DTASN1ParserDelegate> delegate

Declared In

DTASN1Parser.h

parserError

Returns an NSError object from which you can obtain information about a parsing error.

@property (nonatomic, readonly, strong) NSError *parserError

Discussion

You may invoke this method after a parsing operation abnormally terminates to determine the cause of error.

Declared In

DTASN1Parser.h

Instance Methods

abortParsing

Stops the parser object.

- (void)abortParsing

Declared In

DTASN1Parser.h

initWithData:

Initializes the receiver with the ASN1 contents encapsulated in a given data object.

- (id)initWithData:(NSData *)data

Parameters

data

An NSData object containing ASN1 encoded data.

Return Value

An initialized DTASN1Parser object or nil if an error occurs.

Declared In

DTASN1Parser.h

parse

Starts the event-driven parsing operation.

- (BOOL)parse

Return Value

YES if parsing is successful and NO in there is an error or if the parsing operation is aborted.

Discussion

If you invoke this method, the delegate, if it implements parser:parseErrorOccurred:, is informed of the cancelled parsing operation.
