Inheritance diagram for ASN1BERMessageBuffer:
List of all members.
Detailed Description
The ASN1BERMessageBuffer class is derived from the ASN1MessageBuffer base class. It is the base class for the ASN1BEREncodeBuffer and ASN1BERDecodeBuffer derived classes. It contains variables and methods specific to encoding or decoding ASN.1 messages using the Basic Encoding Rules(BER) and Distinguished Encoding Rules (DER).It is used to manage the buffer into which an ASN.1 message is to be encoded or decoded.

|
|
The protected constructor creates a new context and sets the buffer class type. Use getStatus() method to determine has error occured during the initialization or not.
- Parameters:
-
| bufferType | Type of message buffer that is being created (for example, BEREncode or BERDecode). |

This method outputs a formatted binary dump of the current buffer contents to stdout.
Calling Sequence:
messageBuffer.binDump ();
where messageBuffer is an ASN1BERMessageBuffer derived class object. |

|
|
This method calculates the actual length of an indefinite length message component.
Calling Sequence:
len=messageBuffer.calcIndefLen (buf_p);
where messageBuffer is an ASN1BERMessageBuffer derived class object.
- Parameters:
-
| buf_p | A pointer to a message component encoded using indefinite length encoding. |
| bufSize | Size of the buffer buf_p (in octets). |
- Returns:
- Length, in octets, of message component, as int.

[inline] |
|
|
|
This method outputs a hexadecimal dump of the current buffer contents to stdout.
Calling sequence:
messageBuffer.hexDump ();
where messageBuffer is an ASN1BERMessageBuffer derived class object. |
