This class is accessible through :py:class:`PdfReader.metadata`. All text properties of the document metadata have *two* properties, eg. author and author_raw. The non-raw property will always return a ``TextStringObject``, making it ideal for a case where the metadata is being displayed. The raw property can sometimes return a ``ByteStringObject``, if PyPDF2 was unable to decode the string's text encoding; this requires additional safety in the caller and therefore is not as commonly accessed. rDNcCst|dSN)r2__init__selfrIrIrJrOszDocumentInformation.__init__keycCs||d}t|tr |SdSrN)get isinstancer<)rQrRretvalrIrIrJ _get_texts  zDocumentInformation._get_textcCstdd||S)z The text value of the specified key or None. .. deprecated:: 1.28.0 Use the attributes (e.g. :py:attr:`title` / :py:attr:`author`). getText3.0.0)rrV)rQrRrIrIrJrWs  zDocumentInformation.getTextcCs,|tjr|tjp|tjSdS)z Read-only property accessing the document's **title**.
