Constructor & Destructor Documentation

OStream (  String &    buffer,
int    mode = IO_Writable
) 
 

Opens a stream attached to the given string buffer.

Example: 

        String myBuffer;
        OStream(myBuffer) << "Put some text there " << 123 << 42.42 << '\n';
        OStream(myBuffer, IO_Append) << " Some appended text";
Parameters:
buffer  String buffer to use.
mode  (Optional) opening mode. IO_Writable is always enabled, but IO_Append and IO_Truncate may be very useful.

Definition at line 231 of file mstream.cc.

References IO_Writable.

OStream (  FILE *    strm = stdout ) 
 

Parameters:
strm  Already opened FILE stream to use.

Definition at line 209 of file mstream.cc.

OStream (  OStream &    orig ) 
 

Copy constructor.

Definition at line 217 of file mstream.cc.

Member Function Documentation

void copy (  const OStream &    other )  [virtual]
 

Standard copy operation.

Definition at line 246 of file mstream.cc.

References Stream::copy(), and mAutoFlush.

void flush (    ) 
 

Flush the stream.

Definition at line 239 of file mstream.cc.

References IODevice::flush().

OStream & printf (  const char *    sformat,
...   
)  [virtual]
 

Formatted printing to stream.

Note:
The OStream::printf is not very efficient as it prints using a memory buffer. Inheritors should implement it by using device vformat interface.

Reimplemented in TextOStream.
