An observable class that holds a primitive char.
Observable field classes may be used instead of creating an Observable object. It can also create a calculated field, depending on other fields:
public class MyDataObject {
     public final ObservableChar firstInitial = new ObservableChar();
     public final ObservableChar firstInitialCapitalized = new ObservableChar(firstInitial)
         @Override
         public char get() { return Character.toUpperCase(firstInitial.get()); }
     };
 }This class is parcelable and serializable but callbacks are ignored when the object is parcelled / serialized. Unless you add custom callbacks, this will not be an issue because data binding framework always re-registers callbacks when the view is bound. A parceled ObservableChar will lose its dependencies.

Fields
Public constructors
ObservableChar
ObservableChar (char value)
Creates an ObservableChar with the given initial value.
| Parameters | |
|---|---|
| value | char: the initial value for the ObservableChar | 
ObservableChar
ObservableChar ()
Creates an ObservableChar with the initial value of 0.
ObservableChar
ObservableChar (Observable... dependencies)
Creates an ObservableChar that depends on dependencies. Typically,
 ObservableFields are passed as dependencies. When any dependency
 notifies changes, this ObservableChar also notifies a change.
| Parameters | |
|---|---|
| dependencies | Observable: The Observables that this ObservableChar depends on. |
