Member Function Documentation

String * WriteStream::className (  void   )  const [virtual]
 

Answer receiver class name.

Because there isn't any standard way to obtain class name this method comes to place.

Every class should rewrite this method but many didn't (yet).

Reimplemented from Core::InternalStream.

Definition at line 35 of file WriteStream.cc.

00036 {
00037     return new String("WriteStream");
00038 }

SequenceableCollection * WriteStream::contents (  void   )  [virtual]
 

Answer content of the receiver.

In many cases it doesn't matter if it is ReadStream or WriteStream because they don't do any conversion. I does matter on streams like EncodedStream where some conversion takes place. In that case contents() always answer collection of encoded data (for ex. as it would be written to the disk). To get all data decoded you can use upToEnd() method.
