Detailed Description

template<typename Container>
class pdfobjects::CStreamsXpdfReader< Container >

Adapter which is able to read sequentially from more cstreams.

It stores a container of streams and when the actual stream does not contain more objects, tries to read the next one if any.

This class is an example of Adapter design pattern. We have to be able to read from more streams sequentially and this class provides us with the interface.

template<typename Container >
template<typename Ctr >
void pdfobjects::CStreamsXpdfReader< Container >::close ( Ctr &  parsedstreams  )  [inline]

Close. Save parsed streams to container.

Parameters:
parsedstreams Output buffer that will contain all streams we have really parsed.

template<typename Container >
void pdfobjects::CStreamsXpdfReader< Container >::close (  )  [inline]

Close.

template<typename Container >
bool pdfobjects::CStreamsXpdfReader< Container >::eof (  )  [inline]

Is end of all streams.

We can not cache and due to this fact we can not tell if a stream is empty without fetching an object.

References pdfobjects::CStreamsXpdfReader< Container >::curobj.

template<typename Container >
bool pdfobjects::CStreamsXpdfReader< Container >::eofOfActualStream (  )  [inline]

Are we at the end of actual stream. We need to ask parser, because of object caching.

References pdfobjects::CStreamsXpdfReader< Container >::parser.

template<typename Container >
void pdfobjects::CStreamsXpdfReader< Container >::getXpdfObject ( ::Object &  obj  )  [inline]

Get xpdf object.

Exceptions:
MalformedFormatExeption if not able to parse object.

template<typename Container >
::Stream* pdfobjects::CStreamsXpdfReader< Container >::getXpdfStream (  )  [inline]

Get xpdf stream.

References pdfobjects::CStreamsXpdfReader< Container >::parser.

template<typename Container >
void pdfobjects::CStreamsXpdfReader< Container >::lookXpdfObject ( ::Object &  obj  )  [inline]

Look at next xpdf object. It need not return the real next object, but it does at the start of a stream.

References pdfobjects::CStreamsXpdfReader< Container >::parser.

template<typename Container >
void pdfobjects::CStreamsXpdfReader< Container >::open (  )  [inline]

Open.
