         public FileRegistryI createFileRegistry(File, int);
         private void initialize(File, int);

    }

The master FileRegistryFactoryI, which is called by FileRegistry to create an object implementing the FileRegistryI interface. All calls to FileRegistry will be delegated to the object returned from this class.
This class implements the behavior described at the start of 'FileRegistryFactoryI': it reads the 'jcfactrz.txt' file, and creates each class listed in this file.
Each class listed in 'jcfactrz.txt' should implement the FileRegistryFactoryI interface. This class will create an instance of each class listed in the 'jcfactrz.txt' file and call that object's createFileRegistry() method. If that method returns an object, the object is returned to FileRegistry. Otherwise, it tries the next FileRegistryFactoryI class listed in this file.
If all FileRegistryFactoryI objects return null, a FileRegistryPlain object is created, if possible, and returned to the FileRegistry.

### · createFileRegistry | Summary | Top

       public FileRegistryI createFileRegistry(File curDir,
                                               int creator)

> Implements:
>   createFileRegistry in interface FileRegistryFactoryI

### · initialize | Summary | Top

       private void initialize(File curDir,
                               int creator)

> First, figure out which platform we're running on. Try to create a platform specific object implementing FileRegistryI (such as FileRegistryMSVM or FileRegistryMRJ). If none of the platform-specific objects can be created, try to create a FileRegistryPlain object.

### · tryCreatePlatformObject | Summary | Top

       private void tryCreatePlatformObject(File curDir,
                                            int creator)

> Open the 'jcfactrz.txt' file, and convert this file into an array of Strings. Then, for each of the Strings, which should be the name of a class, create an instance of that class, which should implement the FileRegistryFactoryI interface. Each object is called, and given a chance to create a FileRegistryI object. If it does create such an object, we're done. The instance variable 'obj' is set by this method.

> For instance, with 'jcfactrz.txt' having its default values, this method will create a 'FileRegistryFactoryWin' object, and then call its 'createFileRegistry()' method. If this method return null, we keep searching. Otherwise, it will return a 'FileRegistryMSVM' object, and we're done.

### · tryCreatePlainObject | Summary | Top

       private void tryCreatePlainObject(File curDir,
                                         int creator)

> Create a FileRegistryPlain object.
