Interface FileLookup

All Known Implementing Classes:
AbstractFileLookup, FileLookupFactory.DefaultFileLookup, OsgiFileLookup

public interface FileLookup

Holds the logic of looking up a file, in the following sequence:

  1. try to load it with the current thread's context ClassLoader
  2. if fails, the system ClassLoader
  3. if fails, try to load it as a file from the disk

Use FileLookupFactory to obtain an instance of FileLookup. This will result in an extended version of FileLookup being used if in an OSGI environment.
