This class is the base class for the hierarchy of exceptions in the Essential Tools Module. (See the section on error reporting and handling in the Essential Tools Module User's Guide.) Although the entire class is documented here, your code usually should not create or directly throw RWxmsg objects. Instead, you should expect to write code that may catch an RWxmsg or one of its derived classes.
RWxmsg provides a basic interface for exceptions, from which an exception string is always available. This exception string is obtained through the why() method, and is represented as a const char*
, single-byte character sequence.
RWxmsg::RWxmsg | ( | const char * | msg | ) |
Creates an exception that returns msg when its why() method is called.
RWxmsg::RWxmsg | ( | const RWxmsg & | msg | ) |
Copy constructor.
RWxmsg::RWxmsg | ( | RWxmsg && | msg | ) |
Move constructor. The constructed instance takes ownership of the data owned by msg.
|
protected |
Creates an exception that returns msg when its why() method is called. If doCopy is true
, copies msg into a new buffer on the heap, otherwise simply keeps a pointer to the given location of msg.
Move assignment. Self takes ownership of the data owned by msg.
|
virtual |
Throws self.

void RWxmsg::swap | ( | RWxmsg & | rhs | ) |
Swaps the data owned by self with the data owned by rhs.
|
virtual |
Returns the message string contained in self.
