Detailed Description

Named event handler base class. This is the base class from which user-defined event handler classes are derived. These classes can be used to handle events during the parsing of an ASN.1 message. The event callback methods that can be implemented are startElement, endElement, and contents methods.

Member Function Documentation

virtual void Asn1NamedEventHandler::bitStrValue ( OSUINT32  numbits,
const OSOCTET *  data 
) [inline, virtual]

This method is invoked from within a decode function when a value of the BIT STRING ASN.1 type is parsed.

Parameters:
numbits - Number of bits in the parsed value.
data - Pointer to a byte array that contains the bit string data.
Returns:
- none
virtual void Asn1NamedEventHandler::boolValue ( OSBOOL  value  )  [inline, virtual]

This method is invoked from within a decode function when a value of the BOOLEAN ASN.1 type is parsed.

Parameters:
value Parsed value.
Returns:
- none
virtual void Asn1NamedEventHandler::charStrValue ( OSUINT32  nchars,
OS32BITCHAR *  data 
) [inline, virtual]

This method is invoked from within a decode function when a value of one of the 32-bit ASN.1 characer string types is parsed.

This is used for the ASN.1 UniversalString type.

Parameters:
nchars Number of characters in the parsed value.
data Pointer to an array containing 32-bit values. Each 32-bit integer value is a universal character.
Returns:
- none
virtual void Asn1NamedEventHandler::charStrValue ( OSUINT32  nchars,
OSUNICHAR *  data 
) [inline, virtual]

This method is invoked from within a decode function when a value of one of the 16-bit ASN.1 character string types is parsed.

This is used for the ASN.1 BmpString type.

Parameters:
nchars Number of characters in the parsed value.
data Pointer to an array containing 16-bit values. These are represented using unsigned short integer values.
Returns:
- none
virtual void Asn1NamedEventHandler::charStrValue ( OSUINT32  nchars,
const OSUTF8CHAR *  value 
) [inline, virtual]

This method is invoked from within a decode function when a value of a UTF-8 character string type is parsed.

Parameters:
nchars Number of characters in the parsed value.
value A UTF-8 character string.
Returns:
- none
virtual void Asn1NamedEventHandler::charStrValue ( const char *  value  )  [inline, virtual]

This method is invoked from within a decode function when a value of one of the 8-bit ASN.1 character string types is parsed.

Parameters:
value Null terminated character string value.
Returns:
- none
virtual void Asn1NamedEventHandler::endElement ( const char *  name,
int  index 
) [pure virtual]

This method is invoked from within a decode function when parsing is complete on an element of a SEQUENCE, SET, SEQUENCE OF, SET OF, or CHOICE construct.

Parameters:
name For SEQUENCE, SET, or CHOICE, this is the name of the element as defined in the ASN.1 defination. For SEQUENCE OF or SET OF, this is set to the name "element".
index For SEQUENCE, SET, or CHOICE, this is not used and is set to the value -1. For SEQUENCE OF or SET OF, this contains the zero-based index of the element in the conceptual array associated with the construct.
Returns:
- none

Implemented in Asn1NullEventHandler.

virtual void Asn1NamedEventHandler::enumValue ( OSUINT32  value,
const OSUTF8CHAR *  text 
) [inline, virtual]

This method is invoked from within a decode function when a value of the ENUMERATED ASN.1 type is parsed.

Parameters:
value - Parsed enumerated value
text - Textual value of enumerated identifier
Returns:
- none
virtual void Asn1NamedEventHandler::int64Value ( OSINT64  value  )  [inline, virtual]

This method is invoked from within a decode function when a value of the 64-bit INTEGER ASN.1 type is parsed.

Parameters:
value Parsed value.
Returns:
- none
virtual void Asn1NamedEventHandler::intValue ( OSINT32  value  )  [inline, virtual]

This method is invoked from within a decode function when a value of the INTEGER ASN.1 type is parsed.

Parameters:
value Parsed value.
Returns:
- none
virtual void Asn1NamedEventHandler::nullValue (  )  [inline, virtual]

virtual void Asn1NamedEventHandler::octStrValue ( OSUINT32  numocts,
const OSOCTET *  data 
) [inline, virtual]

This method is invoked from within a decode function when a value of one of the OCTET STRING ASN.1 type is parsed.

Parameters:
numocts Number of octets in the parsed value.
data Pointer to byte array containing the octet string data.
Returns:
- none
virtual void Asn1NamedEventHandler::oidValue ( OSUINT32  numSubIds,
OSUINT32 *  pSubIds 
) [inline, virtual]

This method is invoked from within a decode function whn a value the OBJECT IDENTIFIER ASN.1 type is parsed.

Parameters:
numSubIds Number of subidentifiers in the object identifier.
pSubIds Pointer to array containing the subidentifier values.
Returns:
-none
virtual void Asn1NamedEventHandler::openTypeValue ( OSUINT32  numocts,
const OSOCTET *  data 
) [inline, virtual]

This value is invoked from within a decode function when an ASN.1 open type is parsed.

Parameters:
numocts Number of octets in the parsed value.
data Pointer to byet array contain in tencoded ASN.1 value.
Returns:
- none
virtual void Asn1NamedEventHandler::realValue ( double  value  )  [inline, virtual]

This method is invoked from within a decode function when a value the REAL ASN.1 type is parsed.

Parameters:

Returns:
- none
virtual void Asn1NamedEventHandler::startElement ( const char *  name,
int  index 
) [pure virtual]

This method is invoked from within a decode function when an element of a SEQUENCE, SET, SEQUENCE OF, SET OF, or CHOICE construct is parsed.

Parameters:
name For SEQUENCE, SET, or CHOICE, this is the name of the element as defined in the ASN.1 defination. For SEQUENCE OF or SET OF, this is set to the name "element".
index For SEQUENCE, SET, or CHOICE, this is not used and is set to the value -1. For SEQUENCE OF or SET OF, this contains the zero-based index of the element in the conceptual array associated with the construct.
Returns:
- none

Implemented in Asn1NullEventHandler.

virtual void Asn1NamedEventHandler::uInt64Value ( OSUINT64  value  )  [inline, virtual]

This method is invoked from within a decode function when a value of the 64-bit INTEGER ASN.1 type is parsed.

Parameters:
value Parsed value.
Returns:
