public static void openFile(Path fileToOpen,
                            DataHandlerRegistry dataHandlerRegistry,
                            FileExtensionDescriptorRegistry fileExtensionDescriptorRegistry,
                            DocumentHandlerDescriptorRegistry documentHandlerDescriptorRegistry,

                            ContextInjector contextInjector)

Opens a file. This method looks first in the DataHandlerRegistry if there is already a registered DataHandler for the specified file path and uses it if available.

If the DataHandlerRegistry does not contain an according DataHandler, this method looks in the FileExtensionDescriptorRegistry if there is any registered FileExtensionDescriptor for the file extension of the file to open. If one is registered this method then looks looks in the DocumentHandlerDescriptorRegistry if there is any DocumentHandlerDescriptor for the associated MIME type. It then tries to create a DataHandler for the specified file path and register it in the DataHandlerRegistry.

Once it has found or created a DataHandler it looks if there's an Openable registered in the local Context of the DataHandler. If it finds an Openable it calls Openable.open().

Parameters:

fileToOpen - the path to the file to open.

dataHandlerRegistry - the data handler registry

fileExtensionDescriptorRegistry - the file extension descriptor registry

documentHandlerDescriptorRegistry - the document handler descriptor registry

contextManager - the context manager

contextInjector - the context injector
