/// info

`File` is a class that inherits directly from `Form`.

But remember that when you import `Query`, `Path`, `File` and others from `fastapi`, those are actually functions that return special classes.

## Advanced description from docstring

You can limit the lines used from the docstring of a *path operation function* for OpenAPI.

Adding an `\f` (an escaped "form feed" character) causes **FastAPI** to truncate the output used for OpenAPI at this point.

It won't show up in the documentation, but other tools (such as Sphinx) will be able to use the rest.

```Python hl_lines="19-29"

    assertEquals("abc.d.Abc", ClassPath.getClassName("abc/d/Abc.class"));
  }

  public void testResourceInfo_of() {
    assertEquals(ClassInfo.class, resourceInfo(ClassPathTest.class).getClass());
    assertEquals(ClassInfo.class, resourceInfo(ClassPath.class).getClass());
    assertEquals(ClassInfo.class, resourceInfo(Nested.class).getClass());
  }

  public void testGetSimpleName() {

}

func (b *streamingBitrotWriter) Close() error {
	// Close the underlying writer.
	// This will also flush the ring buffer if used.
	err := b.iow.Close()

	// Wait for all data to be written before returning else it causes race conditions.
	// Race condition is because of io.PipeWriter implementation. i.e consider the following
	// sequent of operations:
	// 1) pipe.Write()
	// 2) pipe.Close()
