Public Member Functions | ||||
virtual int64_t | increment (int64_t c=1) | |||
Incremenet the value by c, and return the new value. | ||||
virtual int64_t | postIncrement (int64_t c=1) | |||
Incremenet the value by c, and return the original value. | ||||
virtual int64_t | decrement (int64_t c=1) | |||
Decrement the value by c, and return the new value. | ||||
virtual int64_t | postDecrement (int64_t c=1) | |||
Decrement the value by c, and return the original value. | ||||
virtual int64_t | getCount () const | |||
Return the current value of the counter. | ||||
virtual int64_t | update (int64_t cAssume, int64_t cNew) | |||
Update the current value, only if it is equal to the assumed value. | ||||
virtual int64_t | setCount (int64_t cNew) | |||
Update the current value, and return the previous value. | ||||
virtual void | toStream (std::ostream &out) const | |||
Output a human-readable description of this Object to the given stream. coherence::lang::operator<<(std::ostream, Object::View) is defined and will call into the toStream method, to output Objects. If a managed String object is desired, the COH_TO_STRING macro can be used to build up a String from streamable contents.
Object::View vKey = ... Object::View vValue = ... std::cout << vKey << " = " << vValue << std::endl; String::Handle hs = COH_TO_STRING(vKey << " = " << vValue);
