- - ### Field Detail

    - #### _filenameFilter

          protected final FilenameFilter _filenameFilter

  - ### Constructor Detail

    - #### ScanningAppProvider

  - ### Method Detail

    - #### getDeployedApps

          protected Map<String,App> getDeployedApps()

      Returns:

    - #### createApp

          protected App createApp(String filename)

      Called by the Scanner.DiscreteListener to create a new App object. Isolated in a method so that it is possible to override the default App object for specialized implementations of the AppProvider.

      Returns:
        The App object for this particular context definition file.
