Interface IFileContentManager

public interface IFileContentManager
This is the API to define mappings between file names, file extensions and content types, typically used by repository providers in order to determine whether a given file can be treated as text or must be considered binary. Mappings for names and extensions can either be contributed via an extension point or via this interface. For methods that determine the content type for a given file, the following rules apply:
  • Mappings for the entire file name take precedence over mappings for the file extension only.
  • User-defined mappings take precedence over plugin-contributed mappings
If a mapping is added for a name or an extension that already has a mapping which has been contributed by a plugin, it overrides the one contributed by the plugin. If the user-defined mapping is deleted, the plugin-contributed mapping is valid again. This interface is not intended to be implemented by clients.

  • Method Details

    • getType

      int getType(IStorage storage)
      Get the content type for a given instance of IStorage. User-defined mappings take precedence over plugin-contributed mappings; further, mappings for the entire file name take precedence over mappings for the file extension only.
      Parameters:
      storage - the instance of IStorage.
      Returns:
      one of Team.UNKNOWN, Team.TEXT or Team.BINARY.
      Since:
      3.1

    • isKnownFilename

      boolean isKnownFilename(String filename)
      Check whether the given file name is assigned to a specific type in the content type registry.
      Parameters:
      filename - the file name to check for
      Returns:
      True if the file name is registered in the system and assigned to a content type, false if the file name is unknown.
      Since:
      3.1

    • isKnownExtension

      boolean isKnownExtension(String extension)
      Check whether the given file extension is assigned to a specific type in the content type registry.
      Parameters:
      extension - the extension to check for
      Returns:
      True if the extension is registered in the system and assigned to a content type, false if the extension is unknown.
