Inheritance diagram for SExpressionStream:
This class just provides interface for streams, that is, declares operations common for all existing streams.
Definition at line 39 of file sstream.hpp.
Public Member Functions | |
SExpressionStream () | |
The constructor. | |
virtual SString | TextRepresentation () |
virtual int | Getc ()=0 |

perform positioning operation (like lseek(fd, pos, SEEK_SET)) | |
virtual long | Tell ()=0 |
return the current position | |
virtual int | Close ()=0 |
close the stream | |
virtual int | Flush ()=0 |
perform flush operation if it is supported | |
virtual int | Fileno ()=0 |
returns the corresponding file descriptor, or -1 if none | |

Are the two objects EQL (while not EQ). This function is overriden by those SExpressions able to be EQL while being not EQ.

Is it OK to delete the object now? Our children have no access to the private attribute RefCount and should never need it except when checking if the destruction is not an error. This solves the problem. Definition at line 53 of file refcount.hpp. |
