SimpleStringProperty set() vs. setValue()

Question

What is the difference between `set(String)` and `setValue(String)` in the `SimpleStringProperty` class? I know that `set(String)` is derived from `StringPropertyBase`, but this makes me even more wonder, why there additionally is `setValue(String)`?

Accepted Answer

`set/setValue` and `get/getValue` methods pairs exist to align Object properties with primitive types properties like `BooleanProperty` or `DoubleProperty`:

BooleanProperty:

```
void set(boolean value)
void setValue(java.lang.Boolean v)
```

DoubleProperty:

```
void set(double value)
void setValue(java.lang.Number v)
```

In these property classes `___Value` methods work with corresponding to type objects while direct methods work with primitive types.

Looking in the code you may find a bit of a difference in the logic. For example, `DoubleProperty#setValue(null)` is equal to `DoubleProperty#set(0.0)` (which was required by binding). So generally I'd advise to use set/get methods and leave setValue/getValue to binding needs as they may incorporate additional logic.

For Object/String properties there is no difference between set and setValue methods.
