/**
 * An abstraction to access a file to be deployed along with the application via
 * the class loader.
 * 

* The file is searched in the class loader with getResourceAsStream(x) where x * is one of *

    *
  • [path]/[os.name]-[os.arch]/[filename]
  • *
  • [path]/[os.short name]-[os.arch]/[filename]
  • *
  • [path]/default/[filename]
  • *
* * where * *
    *
  • [path] is a path prefix defined upon object creation
  • *
  • [os.name] is the System property os.name in lowercase
  • *
  • [os.short name] is derived from the System property os.name by using the * beginning up to the first whitespace in lowercase
  • *
  • [os.arch] is the System property os.arch in lowercase
  • *
  • [filename] is the name defined upon object creation
  • *
* * example, with NativeCode("foo", "bar.dll") on a Windows Vista machine you * will search for: * *
    *
  • foo/windows vista-x86/bar.dll
  • *
  • foo/windows-x86/bar.dll
  • *
  • foo/default/bar.dll
