Asn1OpenExt Class Reference

Inheritance diagram for Asn1OpenExt:

Asn1Type Asn1TypeIF List of all members.

Detailed Description

This is a container class for holding open type elements that may occur within an open type extension (i.e. a ... at the end of a constructed type or a ..., ... at some other point in a constructed type).

Member Function Documentation

override void Decode Asn1PerDecodeBuffer  buffer  )  [virtual]
 

This method decodes an open type extension in a SEQUENCE or SET construct using the packed encoding rules (PER). This method will capture each extension item in a separate open type object and store it in the mValue public member list variable. If optional items are absent, null placeholders will be inserted in the list.

Parameters:
buffer Decode message buffer object

Reimplemented from Asn1Type.

override void Decode Asn1BerDecodeBuffer  buffer,
bool  explicitTagging,
int  implicitLength
[virtual]
 

This method decodes an ASN.1 open type extension value using the Basic Encoding Rules (BER).

Parameters:
buffer Decode message buffer object
explicitTagging Flag indicating element is explicitly tagged
implicitLength Length if implicit element

Reimplemented from Asn1Type.

virtual void DecodeComponent Asn1BerDecodeBuffer  buffer  )  [virtual]
 

This method decodes a single component of a BER open type extension by decoding an open type value and appending it to the list of open type objects.

Parameters:
buffer Decode message buffer object

virtual void DecodeEventComponent Asn1BerDecodeBuffer  buffer  )  [virtual]
 

This method decodes a single component of a BER open type extension by decoding an open type value and appending it to the list of open type objects, this function also triggers event handler code, with element name "..."

Parameters:
buffer Decode message buffer object

virtual Asn1OpenType DecodeOpenType Asn1PerDecodeBuffer  buffer,
bool  present,
int  index
[virtual]
 

This method decodes a single open type extension item in a SEQUENCE or SET construct using the packed encoding rules (PER). It will then add the item to the open extension element list.

Parameters:
buffer Decode message buffer object
present Flag indicating whether element is present
index Index of element in the object array
Returns:
Decoded open type

override void Encode Asn1PerOutputStream  outs  )  [virtual]
 

This method encodes an ASN.1 open type extension value using the Packed Encoding Rules (PER).

Also throws any exception thrown by the underlying Asn1PerOutputStream.

Parameters:
outs PER Output Stream object
Exceptions:
Asn1Exception Thrown, if operation is failed.

Reimplemented from Asn1Type.

override void Encode Asn1BerOutputStream  outs,
bool  explicitTagging
[virtual]
 

This method encodes an ASN.1 open type extension value using the Basic Encoding Rules (BER) and writes it into the stream.

Also throws any exception thrown by the underlying Asn1BerOutputStream.

Parameters:
outs BER Output Stream object
explicitTagging Flag indicating element is explicitly tagged
Exceptions:
Asn1Exception Thrown, if operation is failed.

Reimplemented from Asn1Type.

override void Encode Asn1XerEncoder  buffer  )  [virtual]
 

This method encodes an ASN.1 open type extension value using the XML Encoding Rules (XER).

Parameters:
buffer Encode message buffer object

Reimplemented from Asn1Type.

override void Encode Asn1PerEncodeBuffer  buffer  )  [virtual]
 

This method encodes an ASN.1 open type extension value using the Packed Encoding Rules (PER).

Parameters:
buffer Encode message buffer object

Reimplemented from Asn1Type.

override int Encode Asn1BerEncodeBuffer  buffer,
bool  explicitTagging
[virtual]
 

This method encodes an ASN.1 open type extension value using the Basic Encoding Rules (BER).

Parameters:
buffer Encode message buffer object
explicitTagging Flag indicating element is explicitly tagged
Returns:
Length of encoded component

Reimplemented from Asn1Type.

virtual void EncodeExtBits Asn1PerEncodeBuffer  buffer  )  [virtual]
 

This method encodes an ASN.1 open type extension value bits using the Packed Encoding Rules (PER).

Parameters:
buffer Encode message buffer object

virtual void SetOpenType Asn1OpenType  obj,
int  index
[virtual]
 

This method will add the given open type object to the open extension element list at the given index.

Parameters:
obj Open type object
index Index in open type list where element is to be placed

virtual void ShrinkArray int  numrecs  )  [virtual]
 

This method adjusts the size of the open type component array downward to the given size value.

Parameters:
numrecs Number of entries the array should hold

override System.String ToString  ) 
 

This method will return a string representation of the open extension value. The format is the ASN.1 value format for each open type in the extension.

Returns:
Stringified representation of the value


Member Data Documentation

System.Collections.ArrayList mValue
 

Initial value:

 
         new System.Collections.ArrayList()
The value is a list of Asn1OpenType objects. Each of these objects contains a fully encoded extension item.
