Form (PDFxStream API Reference)

All Superinterfaces:

Iterable<T>

All Known Subinterfaces:

AcroForm
```
public interface Form<T extends FormField>
extends Iterable<T>
```
Provides access to form data available in a PDF document. Currently, the only implementation of this interface is AcroForm, which represents form data held in an interactive AcroForm embedded in some PDF documents.

Conceptually, Forms are collections of key/value pairs, represented by FormFields.
