ViewModelProperty

All Implemented Interfaces:

app.rive.runtime.kotlin.core.RefCount
```
public abstract class ViewModelProperty<T extends Object>
extends NativeObject
                    
```
A property of type T of a ViewModelInstance. Use value to mutate the property. use valueFlow to subscribe to changes on the value.

ViewModelProperty(Long unsafeCppPointer, ReentrantLock fileLock)
```
    Parameters:
    
    unsafeCppPointer - Pointer to the C++ counterpart.
    
    fileLock - Lock shared by the File and native graph this property mutates.
- Method Detail
  - getName
```
 final String getName()
```
  - getValue
```
 final T getValue()
```
  - setValue
```
 final Unit setValue(T value)
```
  - getValueFlow
```
 final <ERROR CLASS> getValueFlow()
```
    A flow of the property's value. Use for observing changes.
  - getHasCppObject
```
 final Boolean getHasCppObject()

  - setRefs
```
 final Unit setRefs(AtomicInteger refs)
```
  - getCppPointer

```
  - setCppPointer
```
 final Unit setCppPointer(Long cppPointer)
```
  - getDependencies
```

  - getRefCount
```
 Integer getRefCount()
```
  - cppName
```
 final String cppName(Long cppPointer)
```
  - cppHasChanged
```
@VisibleForTesting(otherwise = 2) final Boolean cppHasChanged(Long cppPointer)
```
  - release
```
 Integer release()
```
    Release this property while holding the current file lock.
    NativeObject.release is synchronized on this object and subclasses may enter fileLock during cppDelete. Taking the file lock first keeps disposal ordered as file lock -> object monitor -> native delete.
