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.

If this method returns true it doesn't necessarily mean that object must be in the indirect state at any moment, but rather defines that when the object will be written to the document it will be transformed into indirect object if it's not indirect yet.

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

Specified by:

isWrappedObjectMustBeIndirect in class PdfObjectWrapper<PdfString>

Returns:

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