Detailed Description

This class is a base class for other ASN.1 XER input stream's classes. It is derived from the ASN1Stream base class. It contains variables and methods specific to streaming decoding of XER messages. It is used to manage the input stream containing the ASN.1 message to be decoded.

Constructor & Destructor Documentation

ASN1XERInputStream::ASN1XERInputStream (  OSCInputStream &  inputStream  )  [inline]
 

A constructor. Initializes input stream by using OSCInputStream instance. Use getStatus() method to determine has error occured during the initialization or not.

Parameters:
inputStream Input stream object.

ASN1XERInputStream::ASN1XERInputStream (  const ASN1OCTET *  msgbuf,
size_t  numocts
)  [inline]
 

A constructor. Initializes input stream by using memory buffer. Use getStatus() method to determine has error occured during the initialization or not.

Parameters:
msgbuf A pointer to a buffer containing an encoded ASN.1 message.
numocts Size of the message buffer.

Member Function Documentation

int ASN1XERInputStream::decodeObj (  ASN1CType &  val  ) 
 

This method decodes an ASN.1 constructed object from the stream.

Parameters:
val A reference to an object to be decoded.
Returns:
Completion status of operation:
  • 0 (ASN_OK) = success,
  • negative return value is error.

ASN1XERInputStream& ASN1XERInputStream::operator>> (  ASN1CType &  val  ) 
 

Decodes an ASN.1 constructed object from the stream. Use getStatus() method to determine has error occured during the operation or not.

Parameters:
val A reference to an object to be decoded.
Returns:
reference to this class to perform sequential decoding.
