Member Function Documentation

void stdbase::io::FilterInputStream::mark (  int readlimit )  [virtual]

Marks the current position in the input stream incase the caller need return to this point - done by calling reset(). Parameters: readlimit   the maximum limit of bytes before the marked position becomes invalid. Reimplemented from stdbase::io::InputStream. Reimplemented in stdbase::io::BufferedInputStream. Definition at line 71 of file FilterInputStream.cpp.

int stdbase::io::FilterInputStream::read (  )  throw (IOException) [virtual]

Read a single byte from the stream and return it as an integer. Returns: the number of bytes read. Reimplemented from stdbase::io::InputStream. Reimplemented in stdbase::io::BufferedInputStream. Definition at line 116 of file FilterInputStream.cpp.

void stdbase::io::FilterInputStream::reset (  )  throw (IOException) [virtual]

Returns the caller to a previously marked position in the input stream (if supported). Exceptions: IOException   if mark/reset not supported or if the number of bytes read exceeds the mark readlimit when mark() was called. Reimplemented from stdbase::io::InputStream. Reimplemented in stdbase::io::BufferedInputStream. Definition at line 85 of file FilterInputStream.cpp.

long stdbase::io::FilterInputStream::skip (  long n )  throw (IOException) [virtual]

Skip the next n bytes from the input stream. Returns: the number of bytes skipped. Reimplemented from stdbase::io::InputStream. Definition at line 127 of file FilterInputStream.cpp.
