Class PdfDate
PdfDate
is the PDF date object.
PDF defines a standard date format. The PDF date format closely follows the format
defined by the international standard ASN.1 (Abstract Syntax Notation One, defined

of the form:
(D:YYYYMMDDHHmmSSOHH'mm')

isWrappedObjectMustBeIndirect
protected boolean isWrappedObjectMustBeIndirect()Description copied from class:PdfObjectWrapper
Defines if the object behind this wrapper must be an indirect object in the resultant document.

Return value of this method shouldn't depend on any logic, it should return always true or false.- Specified by:
isWrappedObjectMustBeIndirect

- Returns:
- true if in the resultant document the object behind the wrapper must be indirect, otherwise false.
