oeiwrapperstream

class oeiwrapperstream : public oeistream

This class represents oeiwrapperstream.

Implements a wrapper class to seamless contain and abstract the functionality of another oeistream.

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

The following classes derive from this class:

• oeigzstream

• oeprogressstream

Constructors

oeiwrapperstream()
oeiwrapperstream(oeistream *isptr, bool del)

Creates a new oeiwrapperstream. 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 (oeiwrapperstream::set), the wrapped stream will be deleted before it is cleared.

set

bool set(oeistream *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

oeistream *stream()

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