ASN1PERMessageBuffer Class Reference [PER Message Buffer Classes] #include <asn1PerCppTypes.h> Inheritance diagram for ASN1PERMessageBuffer: List of all members. Detailed Description The ASN1PERMessageBuffer class is derived from the ASN1MessageBuffer base class. It is the base class for the ASN1PEREncodeBuffer and ASN1PERDecodeBuffer derived classes. It contains variables and methods specific to encoding or decoding ASN.1 messages using the Packed Encoding Rules (PER). It is used to manage the buffer into which an ASN.1 message is to be encoded or decoded. Public Member Functions void  binDump (const char *varname) void  hexDump () size_t  getMsgLen () void  setTrace (ASN1BOOL value) int  setBuffer (const ASN1OCTET *pMsgBuf, size_t msgBufLen) void  BinDump (const char *varname) void  HexDump () int  GetMsgLen () void  SetTrace (ASN1BOOL value) Protected Member Functions   ASN1PERMessageBuffer (Type bufferType, ASN1BOOL aligned)   ASN1PERMessageBuffer (Type bufferType, ASN1OCTET *pMsgBuf, size_t msgBufLen, ASN1BOOL aligned) Constructor & Destructor Documentation ASN1PERMessageBuffer::ASN1PERMessageBuffer (  Type  bufferType, ASN1BOOL  aligned )  [protected]   This constructor does not set a PER input source. It is used by the derived encode buffer classes. Use the getStatus() method to determine if an error has occured during initialization. Parameters: bufferType  Type of message buffer that is being created (for example, PEREncode or PERDecode). aligned  Flag indicating if aligned (TRUE) or unaligned (FALSE) encoding should be done. ASN1PERMessageBuffer::ASN1PERMessageBuffer (  Type  bufferType, ASN1OCTET *  pMsgBuf, size_t  msgBufLen, ASN1BOOL  aligned )  [protected]   This constructor allows a memory buffer holding a binary PER message to be specified. Use the getStatus() method to determine if an error has occured during initialization. Parameters: bufferType  Type of message buffer that is being created (for example, PEREncode or PERDecode). pMsgBuf  A pointer to a fixed size message buffer to recieve the encoded message. msgBufLen  Size of the fixed-size message buffer. aligned  Flag indicating if aligned (TRUE) or unaligned (FALSE) encoding should be done. Member Function Documentation void ASN1PERMessageBuffer::binDump (  const char *  varname  )  [inline]   This method outputs a binary dump of the current buffer contents to stdout. Parameters: varname  char pointer to current buffer size_t ASN1PERMessageBuffer::getMsgLen (   )  [inline]   This method returns the length of a previously encoded PER message. Parameters: -  none void ASN1PERMessageBuffer::hexDump (   )  [inline]   This method outputs a hexadecimal dump of the current buffer contents to stdout. Parameters: -  none int ASN1PERMessageBuffer::setBuffer (  const ASN1OCTET *  pMsgBuf, size_t  msgBufLen )    This method sets a buffer to receive the encoded message. Parameters: pMsgBuf  A pointer to a memory buffer to use to encode a message. The buffer should be declared as an array of unsigned characters (ASN1OCTETs). This parameter can be set to NULL to specify dynamic encoding (i.e., the encode functions will dynamically allocate a buffer for the message). msgBufLen  The length of the memory buffer in bytes. If pMsgBuf is NULL, this parameter specifies the initial size of the dynamic buffer; if 0 - the default size will be used. Returns: Completion status of operation: 0 (ASN_OK) = success, negative return value is error. void ASN1PERMessageBuffer::setTrace (  ASN1BOOL  value  )  [inline]   This method turns PER diagnostic tracing on or off. This enables the collection of the bit statistics inside the PER library functions that can be displayed using the binDump method. Parameters: value  Boolean value indicating whether tracing should be on (true) or off (false).
