Available methods include: PDFParser, close, getAllObjectKeys, getCatalog, getDecryptor, getObject, getTrailer, getVersion, initSecurity, isEncrypted, parse, parseObjectBody, and 2 additional methods.
All public members are accessible to any Java application after installing the Aspose.PDF FOSS for Java package.
Properties: allObjectKeys, catalog, decryptor, encrypted, trailer, version.
Properties
| Name | Type | Access | Description |
|---|---|---|---|
trailer | PdfDictionary | Read | Returns the trailer dictionary. |
version | float | Read | Returns the PDF version (e.g. |
catalog | PdfDictionary | Read | Returns the root catalog dictionary (the value of /Root in the trailer). |
allObjectKeys | Set<PdfObjectKey> | Read | Returns all known object keys from the cross-reference table. |
encrypted | boolean | Read | Returns true if this document is encrypted. |
decryptor | PDFDecryptor | Read | Returns the active decryptor, if the document was opened successfully with encryption. |
Methods
| Signature | Description |
|---|---|
PDFParser(reader: RandomAccessReader) | Constructs a new PDFParser for the given source. |
parse() | Parses the PDF file structure: header, cross-reference, and trailer. |
getObject(key: PdfObjectKey) → PdfBase | Loads an object by its key (object number + generation number). |
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). |
getDecryptor() → PDFDecryptor | Returns the active decryptor, if the document was opened successfully with encryption. |
resolveReference(obj: PdfBase) → PdfBase | Resolves a PDF object reference to the actual object. |
parseObjectBody() → PdfBase | Parses an object body at the current lexer position. |
close() | Closes the underlying reader, releasing any associated resources. |
