`getObject(objectNumber: int)` → `PdfBase`	Loads an object by object number (generation 0).
`getTrailer()` → `PdfDictionary`	Returns the trailer dictionary.
`getVersion()` → `float`	Returns the PDF version (e.g.
`getCatalog()` → `PdfDictionary`	Returns the root catalog dictionary (the value of /Root in the trailer).
`getAllObjectKeys()` → `Set<PdfObjectKey>`	Returns all known object keys from the cross-reference table.
`initSecurity(password: byte[])`	Initializes decryption if the PDF is encrypted.
`initSecurity(password: byte[], customHandler: ICustomSecurityHandler)`	Initializes decryption if the PDF is encrypted.
`isEncrypted()` → `boolean`	Returns true if this document is encrypted.
`setDecryptor(decryptor: PDFDecryptor)`	Sets the decryptor directly (for testing).
