public class PdfExplicitDestination
extends PdfDestination

This class shall be used for creation of destinations, associated with outline items, annotations or actions within current document. If you need to create a destination, associated with an object in another PDF (e.g. Remote Go-To actions or Embedded Go-To actions), you should use PdfExplicitRemoteGoToDestination class instead. Note that despite methods with integer value for page parameter are deprecated in this class, Adobe Acrobat handles such destinations correctly, but removes them completely from a PDF, when it is saved as an optimized pdf with the "discard-invalid-links" option. Therefore it is strongly recommended to use methods accepting pdfPage instance, if the destination is inside of the current document.

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<PdfObject>

Returns:

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