implements
Serializable
AbstractYes
Base class for PDF objects that live as indirect objects (`X Y obj ... endobj`).
Every PdfObject gets an object number assigned by ObjectRegistry when registered with a writer. Unlike plain Serializable types (which serialize inline), PdfObjects can be referenced from anywhere in the document via PdfReference.
