Used internally by the Value class as the base class for its shared value objects.
The Value class is essentially a reference-counted pointer to a shared instance of a ValueSource object. If you're feeling adventurous, you can create your own custom ValueSource classes to allow Value objects to represent your own custom data items.
| Value::ValueSource::ValueSource | ( | ) |
| virtual Value::ValueSource::~ValueSource | ( | ) | [virtual] |
| virtual var Value::ValueSource::getValue | ( | ) | const [pure virtual] |
Returns the current value of this object.
| virtual void Value::ValueSource::setValue | ( | const var & | newValue ) | [pure virtual] |
Changes the current value.
This must also trigger a change message if the value actually changes.
| void Value::ValueSource::sendChangeMessage | ( | bool | dispatchSynchronously ) |
Delivers a change message to all the listeners that are registered with this value.
If dispatchSynchronously is true, the method will call all the listeners before returning; otherwise it'll dispatch a message and make the call later.
| void Value::ValueSource::handleAsyncUpdate | ( | ) | [protected, virtual] |
Called back to do whatever your class needs to do.
This method is called by the message thread at the next convenient time after the triggerAsyncUpdate() method has been called.
Implements AsyncUpdater.
