oeistdstream¶
class oeistdstream : public oeistream
This class represents oeistdstream.
Implements a wrapper stream around a standard C++ input stream
(std::istream).
The following methods are publicly inherited from oeistream:

Constructors¶
oeistdstream()
oeistdstream(std::istream *isptr, bool del)
Creates a new oeistdstream. Passing the ‘isptr’
and ‘del’ parameters is
equivalent to using the default constructor and then calling
set(isptr, del) on the
newly created stream.
clear¶
void clear()
Clears the pointer to the wrapped stream. If the ‘del’ parameter was
set to true when the wrapped stream was set
(oeistdstream::set), the wrapped stream
will be deleted before it is cleared.
set¶
bool set(std::istream *isptr, bool del)
Sets ‘isptr’ to be the stream wrapped by this class. If ‘del’ is true,
the wrapped stream will be deleted when the clear method is called
or when this class is deleted. It is important to understand that
by setting ‘del’ to true, ownership of the stream’s memory is
transferred to this class, and if it is false, you retain the
responsibility for managing the stream’s memory.
