Detailed Description
Abstract message buffer or stream interface class.
This is the base class for both the in-memory message buffer classes and the run-time stream classes.

Constructor & Destructor Documentation
| virtual OSRTMessageBufferIF::~OSRTMessageBufferIF | ( | ) | [inline, protected, virtual] |
The virtual destructor does nothing.
It is overridden by derived versions of this class.

Member Function Documentation
| virtual size_t OSRTMessageBufferIF::getByteIndex | ( | ) | [pure virtual] |
The getByteIndex method is used to fetch the current byte offset within the current working buffer.
For encoding, this is the next location that will be written to. For decoding, this is the next byte the parser will read.
Implemented in OSRTMessageBuffer.
| virtual OSOCTET* OSRTMessageBufferIF::getMsgCopy | ( | ) | [pure virtual] |
The getMsgCopy method will return a copy of the encoded ASN.1 message managed by the object.
The memory for the copy is allocated by new [] operator, user is responsible to free it by delete [] operator.
- Returns:
- The pointer to copied encoded ASN.1 message. NULL, if error occurred.
Implemented in OSRTMessageBuffer.
| virtual const OSOCTET* OSRTMessageBufferIF::getMsgPtr | ( | ) | [pure virtual] |
The getMsgPtr method will return a const pointer to the encoded ASN.1 message managed by the object.
- Returns:
- The pointer to the encoded ASN.1 message.
Implemented in OSRTMessageBuffer.
| virtual int OSRTMessageBufferIF::init | ( | ) | [pure virtual] |
Initializes message buffer.
- Returns:
- Completion status of operation:
- 0 (0) = success,
- negative return value is error.
Implemented in OSRTMessageBuffer.
| virtual int OSRTMessageBufferIF::initBuffer | ( | OSOCTET * | pMsgBuf, | |
| size_t | msgBufLen | |||
| ) | [pure virtual] |
This version of the overloaded initBuffer method initializes the message buffer to point at the given null-terminated character string.
- Parameters:
-
pMsgBuf Pointer to message buffer. msgBufLen Length of message buffer in bytes. string.
- Returns:
- Completion status of operation:
- 0 (0) = success,
- negative return value is error.
Implemented in OSRTMessageBuffer.
| virtual OSBOOL OSRTMessageBufferIF::isA | ( | Type | bufferType | ) | [pure virtual] |
This method checks the type of the message buffer.
- Parameters:
-
bufferType Enumerated identifier specifying a derived class. Possible values are: BEREncode, BERDecode, PEREncode, PERDecode, XEREncode, XERDecode, XMLEncode, XMLDecode, Stream.
- Returns:
- Boolean result of the match operation. True if this is the class corresponding to the identifier argument.
| virtual void OSRTMessageBufferIF::setDiag | ( | OSBOOL | value = TRUE |
) | [pure virtual] |
The setDiag method will turn diagnostic tracing on or off.
- Parameters:
-
value - Boolean value (default = TRUE = on)
Implemented in OSRTMessageBuffer.
