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.

stream

std::istream *stream()

Returns a pointer to the wrapped stream if present, otherwise 0.
