List of all members.
Detailed Description
A PdfParserObject constructs a PdfObject from a PDF file. Parsing starts always at the current file position.
Constructor & Destructor Documentation
Parse the object data from the given file handle starting at the current position.
- Parameters:
-
pCreator | pointer to a PdfVecObjects to resolve object references |
rDevice | an open reference counted input device which is positioned in front of the object which is going to be parsed. |
rBuffer | buffer to use for parsing to avoid reallocations |
lOffset | the position in the device from which the object shall be read if lOffset = -1, the object will be read from the current position in the file. |
Parse the object data for an internal object. You have to call ParseDictionaryKeys as next function call.
The following two parameters are used to avoid allocation of a new buffer in PdfSimpleParser.
- Warning:
- This constructor is for internal usage only!
- Parameters:
-
rBuffer | buffer to use for parsing to avoid reallocations |

void PoDoFo::PdfParserObject::DelayedLoadImpl |
( |
| ) |
[protected, virtual] |
void PoDoFo::PdfParserObject::DelayedStreamLoadImpl |
( |
| ) |
[protected, virtual] |
void PoDoFo::PdfParserObject::FreeObjectMemory |
( |
bool |
bForce = false | ) |
|
Tries to free all memory allocated by this PdfObject (variables and streams) and reads it from disk again if it is requested another time.
This will only work if load on demand is used. If the object is dirty if will not be free'd.
- Parameters:
-
bForce | if true the object will be free'd even if IsDirty() returns true. So you will loose any changes made to this object. |
- See also:
- IsLoadOnDemand
-
IsDirty
bool PoDoFo::PdfParserObject::HasStreamToParse |
( |
| ) |
const [inline] |
Returns if this object has a stream object appended. which has to be parsed.
- Returns:
- true if there is a stream
bool PoDoFo::PdfParserObject::IsLoadOnDemand |
( |
| ) |
const [inline] |
- Returns:
- true if this PdfParser loads all objects at the time they are accessed for the first time. The default is to load all object immediately. In this case false is returned.
void PoDoFo::PdfParserObject::ParseFile |
( |
PdfEncrypt * |
pEncrypt, |
|
|
bool |
bIsTrailer = false |
|
) |
| |
Parse the object data from the given file handle If delayed loading is enabled, only the object and generation number is read now and everything else is read later.
- Parameters:
-
pEncrypt | an encryption dictionary which is used to decrypt strings and streams during parsing or NULL if the PDF file was not encrypted |
bIsTrailer | wether this is a trailer dictionary or not. trailer dictionaries do not have a object number etc. |
void PoDoFo::PdfParserObject::ParseStream |
( |
| ) |
[protected] |
Starts reading at the file position m_lStreamOffset and interprets all bytes as contents of the objects stream. It is assumed that the dictionary has a valid /Length key already.
Called from DelayedStreamLoadImpl(). Do not call directly.
void PoDoFo::PdfParserObject::SetLoadOnDemand |
( |
bool |
bDelayed | ) |
[inline] |
Sets wether this object shall be loaded on demand when it's data is accessed for the first time.
- Parameters:
-
bDelayed | if true the object is loaded delayed. |
void PoDoFo::PdfParserObject::SetObjectNumber |
( |
unsigned int |
nObjNo | ) |
[inline] |
Set the object number of this object. It is almost never necessary to use this call. It is only included for usage in the PdfParser.
- Parameters:
-
nObjNo | the new object number of this object |
