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:
| operator>> | gettoken | skipbyte |
| close | open | skipline |
| get | peekbyte | |
| getbyte | read | |
| getline | skip |
The following methods are publicly inherited from oestream:
| operator bool | rewind | tell |
| eof | seek | |
| length | size |
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.
