## Class CompositionTextManager

- Object
- - CompositionTextManager

-     public class CompositionTextManager
      extends Object

  This class Manage texts from input method by begin-process-end steps. First, if a user start inputing via input method, beginCompositionText is called from InputMethodSupport. Second, the user continues from input method, processCompositionText is called and reflect user inputs to text area. Finally the user try to commit text, endCompositionText is called.
