EDIT (again): If anyone is interested, you can follow this issue on the tracker.
EDIT: I know about backing properties and that they will cover most use cases. I'm not looking for a work around, I'm specifically looking if there is a way to name the backing field.
You can easily rename the getter and setter of a property like so
@get:JvmName("getFancy")
@set:JvmName("setFancy")
var fancyProperty = ...
But I can't figure out how to change the name of a backing field, even using the @field target.
@field:JvmName("fancy")
var fancyProperty = ...
The above give an error:
This annotation is not applicable to target 'member property with backing field' and use site target '@field'
Ultimately what I'm going for is interop with JavaFX. When defining a JavaFX property, you usually follow the following standard (with some additional code to make it lazy):
private ObjectProperty<Color> color = new SimpleObjectProperty<>(this, "color", DEFAULT_COLOR);
public ObjectProperty<Color> colorProperty() {
return color;
}
public Color getColor() {
return colorProperty.get();
}
public void setColor(Color color) {
colorProperty().set(color);
}
So what I'm going for is something like this (though the @field obviously doesn't work):
@field:JvmName("color")
@get:JvmName("colorProperty")
val colorProperty: ObjectProperty<Color> =
SimpleObjectProperty(this, "color", DEFAULT_COLOR)
var color
get() = colorProperty.get()
set(value) = colorProperty.set(value)
This would allow the binding capabilities of FXML (which use reflection), follow the standard conventions in Java, and still be nice and easy to use from Kotlin.
In this case I can't use a backing property because I need the color field to be a ObjectProperty<Color>, but the getter and setter for color should be a Color.
Luckily, the reflection from JavaFX is smart enough to still work with just the @get:JvmName("colorProperty"), but there are similar situations with overlapping field names that could use this renaming.
