2022-09-08Rename QPDFValueProxy.hh and QPDFValueProxy.ccJay Berkenbilt
Preparing to change the class name back to QPDFObject
2022-09-08Change reset to disconnect and clarify commentsJay Berkenbilt
I decided that it's actually fine to copy a direct object to another QPDF. Even if we eventually prevent a QPDFObject from having multiple parents, this could happen if an object is moved.
2022-09-08Create a special "destroyed" type rather than using nullJay Berkenbilt
When a QPDF is destroyed, changing indirect objects to direct nulls makes them effectively disappear silently when they sneak into other places. Instead, we should treat this as an error. Adding a destroyed object type makes this possible.
