Detailed Description

This class is the base class for all exceptions thrown in the Server library.

Library: server
and mvcomp

All exceptions that are thrown derive from this class (without adding any new methods) so that it is possible to catch a particular exception using the standard C++ mechanism.

Constructor & Destructor Documentation

◆ IlsException() [1/3]

IlsException::IlsException ( char *  message = 0,
IlsBoolean  destroyMessage = IlsFalse 
)

This constructor creates an instance of IlsException.

If a message is passed in as the first parameter, it can be used via the getMessage member function in the catch statement to print out a message. If the parameter destroyMessage is set to IlsTrue, the message will be deleted (via delete []) when the exception is deleted.

◆ IlsException() [2/3]

IlsException::IlsException ( const char *  message)

This constructor creates an instance of IlsException. The message parameter will not be deleted or copied.

The message can be used via the getMessage() member function in the catch statement to print out a message.

◆ IlsException() [3/3]

IlsException::IlsException ( const IlsException rhs)

This copy constructor copies an instance of a message.

If the message in rhs is marked to be destroyed on deletion of rhs, the message is copied into the new instance.

Member Function Documentation

◆ getMessage()

const char* IlsException::getMessage ( ) const

This member function returns the message, if any, contained in the exception.

This can be used to print an error message, potentially containing extra information, when the exception is caught. An example of this is shown below:

try {
run();
}
catch (IlsOwnershipCycle exc) { // an ownership cycle
}
catch (IlsException exc) { // some other Rogue Wave Server exception
}
catch (...) { // a non Rogue Wave Server exception
}

◆ operator==()

IlsBoolean IlsException::operator== ( const IlsException rhs) const

This copy operator copies the exception rhs.

If the message in rhs is marked to be destroyed on deletion of rhs, then the message is copied into the new instance.

◆ setMessage()

void IlsException::setMessage ( const char *  message)

This member function changes the message in an exception.

If the old message is marked as deletable, then it is deleted and the new message is copied. The message is always copied when this member function is called.
