Public Constructors
RWAuditStreamBuffer(RWauditFunction=0, void*=0);
Constructs a new RWAuditStreamBuffer that may be used only to examine and count
every byte that passes into an ostream that has the RWAuditStreamBuffer instance as its
streambuf. It will not forward the bytes to any stream, nor accept bytes from a stream.
The second argument to the constructor allows you to supply storage for the byte count. It
is optional.
RWAuditStreamBuffer(istream&, RWauditFunction=0, void*=0);
Constructs a new RWAuditStreamBuffer that passes bytes from the istream on which it is
constructed to the istream that has the RWAuditStreamBuffer instance as its streambuf.
A typical use would be to count or examine the bytes being input from a file through a
stream derived from RWvistream. The second argument to the constructor allows you to
supply storage for the byte count. It is optional.
RWAuditStreamBuffer(iostream&, RWauditFunction=0, void*=0);
Constructs a new RWAuditStreamBuffer that passes bytes to and from the iostream on
which it is constructed to and from the istream that has the RWAuditStreamBuffer
instance as its streambuf. A typical use would be to count or examine the bytes being
transferred to and from a file used to store and retrieve changing data. The second
argument to the constructor allows you to supply storage for the byte count. It is optional.
RWAuditStreamBuffer(ostream&, RWauditFunction=0, void*=0);
Constructs a new RWAuditStreamBuffer that passes bytes into the ostream on which it is
constructed from the ostream that has the RWAuditStreamBuffer instance as its
streambuf. A typical use would be to count or examine the bytes being output to a file
through a stream derived from RWvostream. The second argument to the constructor
allows you to supply storage for the byte count. It is optional.
RWAuditStreamBuffer(streambuf*, RWauditFunction=0, void*=0);
Constructs a new RWAuditStreamBuffer that passes bytes into the ostream on which it is
constructed from the ostream that has the RWAuditStreamBuffer instance as its
streambuf. A typical use would be to count or examine the bytes being output to a file
through a stream derived from RWvostream. The second argument to the constructor
allows you to supply storage for the byte count. It is optional.
Public Destructor
virtual ~RWAuditStreamBuffer();
We have provided an empty destructor since some compilers complain if there is no
virtual destructor for a class that has virtual methods.
