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

◆ Asn1BerOutputStream() [1/2]

Asn1BerOutputStream ( System.IO.Stream os )

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.

◆ Asn1BerOutputStream() [2/2]

Asn1BerOutputStream	(	System.IO.Stream	os,
		int	bufSize
	)

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.
