void | resetReferenceCount () noexcept |
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 | ( | ) |

|

Returns the current value of this object.
Implemented in juce::ValueTreePropertyValueSource, juce::SimpleValueSource, and juce::ChoicePropertyComponent::RemapperValueSource.
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.
Changes the current value. This must also trigger a change message if the value actually changes.
Implemented in juce::ValueTreePropertyValueSource, juce::SimpleValueSource, and juce::ChoicePropertyComponent::RemapperValueSource.
