Classes derived from IPV6Address would require an specific validator to pass to the IPV6Address constructor.
The network name and address objects are all derived from a common IPV4Address base class.
The CIDR class is used to support routing tables and validate address policies.
Class for the function object that validates multicast addresses.
This is a base class for classes of function objects used by such derived classes.
Implements a specific application operator to validate multicast addresses.
Specific classes, such as IPV4Host, IPV4Mask, etc, are defined from IPV4Address entirely so that the manner a network address is being used can easily be documented and understood from the code and to avoid common errors and accidental misuse of the wrong address object. For example, a "connection" to something that is declared as a "IPV4Host" can be kept type-safe from a "connection" accidently being made to something that was declared a "IPV4Broadcast".
Implements a specific application operator to validate multicast addresses.
For instance: 0000000 - 77 98 21 49 0e 00 05 00 40 1c 01 1c 2f 00 00 00 w.!I......./...
It uses ost::slog to write to syslog and std::clog to write to standard output.
It provides either a stream oriented logger or a old printf style one.

Used to support ccstd Directory container. This provides a basic mechanism for allocating and accessing file entries.
This class is a foundation both for optimized thread shared and traditional locked file access that is commonly used to build database services, rather than the standard C++ streaming file classes.
SharedFile is used when a database may be shared between multiple processes. SharedFile automatically applies low level byte-range "file locks", and provides an interface to fetch and release byte-range locked portions of a file.
This class is used when a mempager will be shared by multiple threads.
This is used in association with smart pointers (RefPointer).
This is a non-template form of a reference count smart pointer, and so uses common code. This can be subclassed to return explicit object types.
This is used for accumulating lists by using as a base class for a derived subclass.
This is used for accumulating lists by using as a base class for a derived subclass.
Unlike with Assoc, This form of map table also allows objects to be removed from the table. This table also includes a mutex lock for thread safety. A free list is also optionally maintained for reusable maps.
Derived classes may override new and delete operators to use managed free list from a MapTable.
This class manages the types for generation of the persistent objects. Its data structures are managed automatically by the system. They are implicitly filled by the constructors who declare classes to the system.
Base class for classes that will be persistent. This object is the base for all Persistent data which is not natively serialized by the persistence::engine
It registers itself with the persistence::TypeManager using a global constructor function. A matching deregister call is made in a global destructor, to allow DLL's to use the persistence::engine in a main executable.
Persistable objects must never maintain bad pointers. If a pointer doesn't point to something valid, it must be NULL. This is so the persistence engine knows whether to allocate memory for an object or whether the memory has been pre-allocated.
This class constructs on a standard C++ STL stream and then operates in the mode specified. The stream passed into the constructor must be a binary mode to function properly.
These are typically referenced thru Process::xxx static member functions. Many of these members are used both for win32 and posix systems although some may be platform specific.
Peocess wrapper class.
The posix implimentation uses a pidfile and the win32 version uses a globally visible mutex.
A serial is a system serial port that is used either for line or packet based data input. Serial ports may also be "streamable" in a derived form.
Common C++ serial I/O classes are used to manage serial devices and implement serial device protocols. From the point of view of Common C++, serial devices are supported by the underlying Posix specified "termios" call interface.
The serial I/O base class is used to hold a descriptor to a serial device and to provide an exception handling interface for all serial I/O classes. The base class is also used to specify serial I/O properties such as communication speed, flow control, data size, and parity. The "Serial" base class is not itself directly used in application development, however.
Common C++ Serial I/O is itself divided into two conceptual modes; frame oriented and line oriented I/O. Both frame and line oriented I/O makes use of the ability of the underlying tty driver to buffer data and return "ready" status from when select either a specified number of bytes or newline record has been reached by manipulating termios c_cc fields appropriately. This provides some advantage in that a given thread servicing a serial port can block and wait rather than have to continually poll or read each and every byte as soon as it appears at the serial port.
A default slog
object is used to avoid confusion with the native syslog facility and to imply a logical relationship to the C++ clog()
.
The key difference is that the slog
object sends it's output to the system logging daemon (typically syslogd) rather than through stderr. slog
can be streamed with the <<
operator just like clog
; a default slog object is pre-initialized, and you stream character data to it.
The slog
allows one to specify logging levels and other properties through the ()
operators. Hence, once can do:
slog("mydaemon", SLOG_DAEMON, SLOG_EMERGENCY) << I just died << endl;
or things like:
slog("mydaemon", SLOG_DAEMON); slog(SLOG_INFO) << "daemon initalized" << endl;
The intent is to be as common-place and as convenient to use as the stderr based clog facility found in C++, and this is especially useful for C++ daemons.
The std::flush
manipulator doesn't work. Either the std::endl
or std::ends
manipulators must be used to cause the output to be sent to the daemon.
When this class is used on a system that doesn't have the syslog headers (i.e. a non-posix win32 box), the output goes to the a file with the same name as the syslog identifier string with '.log' appended to it. If the identifier string ends in '.exe', the '.exe' is removed before the '.log' is appened. (e.g. the identifier foo.exe will generate a log file named foo.log)
system logging facility class.
A Mutex is used to protect access to the counter variable (an integer). An initial value can be specified for the counter, and it can be manipulated with the ++ and – operators.
It use Mutex to protect operation. Using this class is usefull and exception safe. The mutex that has been locked is automatically released when the function call stack falls out of scope, so one doesnt have to remember to unlock the mutex at each function return.
A common use is
void func_to_protect() { MutexLock lock(mutex); ... operation ... }
NOTE: do not declare variable as "MutexLock (mutex)", the mutex will be released at statement end.
The ThreadLock is automatically released when the object falls out of scope.
A common use is
void func_to_protect() { ReadLock lock(threadlock); ... operation ... }
NOTE: do not declare variable as "ReadLock (threadlock)", the mutex will be released at statement end.
The ThreadLock is automatically released when the object falls out of scope.
A common use is
void func_to_protect() { WriteLock lock(threadlock); ... operation ... }
NOTE: do not declare variable as "WriteLock (threadlock)", the mutex will be released at statement end.
A common use is
void func_to_protect() { SemaphoreLock lock(semaphore); ... operation ... }
NOTE: do not declare variable as "SemaohoreLock (semaphore)", the mutex will be released at statement end.
The class has two purposes:
This is made into a stand-alone base class since other derived libraries (such as the serial handlers) may also use the pooled "service thread" model and hence also require this code for managing timing.
The StringTokenizer takes a pointer to a string and a pointer to a string containing a number of possible delimiters. The StringTokenizer provides an input forward iterator which allows to iterate through all tokens. An iterator behaves like a logical pointer to the tokens, i.e. to shift to the next token, you've to increment the iterator, you get the token by dereferencing the iterator.
Memory consumption: This class operates on the original string and only allocates memory for the individual tokens actually requested, so this class allocates at maximum the space required for the longest token in the given string. Since for each iteration, memory is reclaimed for the last token, you MAY NOT store pointers to them; if you need them afterwards, copy them. You may not modify the original string while you operate on it with the StringTokenizer; the behaviour is undefined in that case.
The iterator has one special method 'nextDelimiter()' which returns a character containing the next delimiter following this tokenization process or '\0', if there are no following delimiters. In case of skipAllDelim, it returns the FIRST delimiter.
With the method 'setDelimiters(const char*)' you may change the set of delimiters. It affects all running iterators.
Example:
StringTokenizer st("mary had a little lamb;its fleece was..", " ;"); StringTokenizer::iterator i; for (i = st.begin() ; i != st.end() ; ++i) { cout << "Token: '" << *i << "'\t"; cout << " next Delim: '" << i.nextDelimiter() << "'" << endl; }
This class implements a basic XML stream parser that can be used to examine an XML resource thru virtual I/O methods. This class must be derived into one that can implement the physical I/O required to parse actual data. A mixer class using XMLParser and tcpstream would be one example of this. This can also be used to parse xml content in memory buffers easily. This parser is only concerned with well-formedness, and does not perform validation.

Set a timeout based on the current time reference value either from object creation or the last setTimer(). This reference can be used to time synchronize realtime data over specified intervals and force expiration when a new frame should be released in a synchronized manner.
timeout | delay in milliseconds from reference. |
Adjust a timeout based on the current time reference value either from object creation or the last setTimer(). This reference can be used to time synchronize realtime data over specified intervals and force expiration when a new frame should be released in a synchronized manner.

Sleep until the current timer expires. This is useful in time syncing realtime periodic tasks.
This is used to "disable" the service thread from expiring the timer object. It does not effect the reference time from either creation or a setTimer().
This is used by service threads to determine how much time remains before the timer expires based on a timeout specified in setTimer() or incTimer(). It can also be called after setting a timeout with incTimer() to see if the current timeout has already expired and hence that the application is already delayed and should skip frame(s).
return time remaining in milliseconds, or TIMEOUT_INF if inactive.
This is used to determine how much time has elapsed since a timer port setTimer benchmark time was initially set. This allows one to use setTimer() to set the timer to the current time and then measure elapsed time from that point forward.

a delimiter string containing all usual whitespace delimiters. These are space, tab, newline, carriage return, formfeed and vertical tab. (see isspace() manpage).
Exception thrown, if someone tried to read beyond the end of the tokens. Will not happen if you use it the 'clean' way with comparison against end(), but if you skip some tokens, because you 'know' they are there. Simplifies error handling a lot, since you can just read your tokens the way you expect it, and if there is some error in the input this Exception will be thrown.
The input forward iterator for tokens.
copy constructor.
assignment operator.
shifts this iterator to the next token in the string.
returns the immutable string this iterator points to or '0' if no token is available (i.e. i == end()). Do not store pointers to this token, since it is invalidated for each iteration. If you need the token, copy it (e.g. with strdup());
returns the next delimiter after the current token or '\0', if there are no following delimiters. It returns the very next delimiter (even if skipAllDelim=true).
compares to other iterator. Usually used to compare against the end() iterator.

delim | String containing the characters which should be regarded as delimiters. |
skipAllDelim | OPTIONAL. true, if subsequent delimiters should be skipped at once or false, if empty tokens should be returned for two delimiters with no other text inbetween. The first behaviour may be desirable for whitespace skipping, the second for input with delimited entry e.g. /etc/passwd like files or CSV input. NOTE, that 'true' here resembles the ANSI-C strtok(char *s,char *d) behaviour. DEFAULT = false |
trim | OPTIONAL. true, if the tokens returned should be trimmed, so that they don't have any whitespaces at the beginning or end. Whitespaces are any of the characters defined in StringTokenizer::SPACE. If delim itself is StringTokenizer::SPACE, this will result in a behaviour with skipAllDelim = true. DEFAULT = false |
create a new StringTokenizer which splits the input string at whitespaces. The tokens are stripped from whitespaces. This means, if you change the set of delimiters in either the 'begin(const char *delim)' method or in 'setDelimiters()', you then get whitespace trimmed tokens, delimited by the new set. Behaves like StringTokenizer(s, StringTokenizer::SPACE,false,true);
