Asn1BerOutputStream Class ReferenceInheritance diagram for Asn1BerOutputStream:
List of all members.
Detailed Description
This class implements the output stream to encode ASN.1 messages as specified in the Basic Encoding Rules (BER) as specified in the ITU-T X.690 standard. A reference to an object of this type is passed to each of the ASN.1 type encode methods involved in encoding a particular message type.

Constructor & Destructor Documentation
|
|
This constructor creates a buffered BER output stream object with default size of buffer. Whenever the buffer becomes full, the buffer will be flushed to the stream.
- Parameters:
-
| os | The underlying System.IO.Stream object. |

This constructor creates a buffered BER output stream object. Whenever the buffer becomes full, the buffer will be flushed to the stream.
- Parameters:
-
| os | The underlying System.IO.Stream object. |
| bufSize | The buffer size. If it is 0 then the output stream is used as unbuffered one. |
