Member Function Documentation

virtual int PLearn::IntStream::current (   )  [inline, virtual]

return next available int from the stream Reimplemented in PLearn::FilesIntStream, and PLearn::InMemoryIntStream. Definition at line 74 of file IntStream.h.

virtual int PLearn::IntStream::next (   )  [inline, virtual]

return currently available int from the stream (at currente position) and THEN increment position to NEXT item Reimplemented in PLearn::FilesIntStream, and PLearn::InMemoryIntStream. Definition at line 71 of file IntStream.h. Referenced by PLearn::InMemoryIntStream::InMemoryIntStream().

virtual int PLearn::IntStream::position (   )  [inline, virtual]

current position (= size if we are past the last read element) Definition at line 80 of file IntStream.h. References pos. Referenced by remaining().

virtual long PLearn::IntStream::remaining (   )  [inline, virtual]

remaining int's (INCLUDING the current one), = 0 if none left to read Definition at line 83 of file IntStream.h. References position(), and size().

virtual void PLearn::IntStream::reopen (   )  [inline, virtual]

Re-open all the file pointers and seek(position()). This is useful when a forked child process wants access to the same stream without interfering with parent Reimplemented in PLearn::FilesIntStream. Definition at line 89 of file IntStream.h.

virtual void PLearn::IntStream::seek (  long  position  )  [inline, virtual]

move to given position Reimplemented in PLearn::FilesIntStream, and PLearn::InMemoryIntStream. Definition at line 67 of file IntStream.h. References PLERROR, and seek(). Referenced by seek().

virtual long PLearn::IntStream::size (   )  [inline, virtual]

total length of the stream Reimplemented in PLearn::FilesIntStream, and PLearn::InMemoryIntStream. Definition at line 77 of file IntStream.h. Referenced by PLearn::InMemoryIntStream::InMemoryIntStream(), and remaining().
