Member Function Documentation

valid()

virtual bool mootio::mzstream::valid ( void  )

inlinevirtual

Test stream integrity

Reimplemented from mootio::mstream.

Referenced by mootio::mzfstream::reopen().

eof()

virtual bool mootio::mzstream::eof ( void  )

inlinevirtual

Test for eof

Reimplemented from mootio::mstream.

errmsg()

virtual std::string mootio::mzstream::errmsg ( void  )

inlinevirtual

Get current error message

Reimplemented from mootio::mstream.

reopen()

virtual bool mootio::mzstream::reopen ( void  )

inlinevirtual

Does nothing

Reimplemented from mootio::mstream.

Reimplemented in mootio::mzfstream.

Referenced by mootio::mzfstream::open().

close()

virtual bool mootio::mzstream::close ( void  )

inlinevirtual

Just resets internal gzFile to NULL, does nothing else

Reimplemented from mootio::mstream.

Reimplemented in mootio::mzfstream.

Referenced by mootio::mzfstream::reopen(), mootio::mizfstream::~mizfstream(), mootio::mozfstream::~mozfstream(), and mootio::mzfstream::~mzfstream().

read()

virtual ByteCount mootio::mzstream::read ( char *  buf, size_t  n  )

inlinevirtual

Read up to n bytes of data into buf, returns number of bytes actually read.

Reimplemented from mootio::mistream.

getbyte()

virtual int mootio::mzstream::getbyte ( void  )

inlinevirtual

Read a single byte of data. Returns EOF on eof.

Reimplemented from mootio::mistream.

References zfile.

flush()

virtual bool mootio::mzstream::flush ( void  )

inlinevirtual

Flush all pending writes (degrades compression ratio).

Reimplemented from mootio::mostream.

write()

virtual bool mootio::mzstream::write ( const char *  buf, size_t  n  )

inlinevirtual

Write n bytes from buf to the stream

Reimplemented from mootio::mostream.

putbyte()

virtual bool mootio::mzstream::putbyte ( unsigned char  c )

inlinevirtual

Write a single byte to the stream

Reimplemented from mootio::mostream.

puts() [1/2]

virtual bool mootio::mzstream::puts ( const char *  s )

inlinevirtual

Write a C string to the stream

Reimplemented from mootio::mostream.

puts() [2/2]

virtual bool mootio::mzstream::puts ( const std::string &  s )

inlinevirtual

Write a C++ string to the stream

Reimplemented from mootio::mostream.
