  • Method Details

    • getInheritableAttribute

      protected COSBase getInheritableAttribute(COSName key)
      Returns the given attribute, inheriting from parent nodes if necessary.
      Parameters:
      key - the key to look up
      Returns:
      COS value for the given key
    • getFieldType

      public abstract String getFieldType()
      Get the FT entry of the field. This is a read only field and is set depending on the actual type. The field type is an inheritable attribute.
      Returns:
      The Field type.
    • getValueAsString

      public abstract String getValueAsString()
      Returns a string representation of the "V" entry, or an empty string.
      Returns:
      The list of widget annotations.
    • setValue

      public abstract void setValue(String value) throws IOException
      Sets the value of the field.
      Parameters:
      value - the new field value.
      Throws:
      IOException - if the value could not be set
    • getWidgets

      public abstract List<PDAnnotationWidget> getWidgets()
      Returns the widget annotations associated with this field. For PDNonTerminalField the list will be empty as non terminal fields have no visual representation in the form.
      Returns:
      a List of PDAnnotationWidget annotations. Be aware that this list is not backed by the actual widget collection of the field, so adding or deleting has no effect on the PDF document. For PDTerminalField you'd have to call setWidgets() with the modified list.
