Detailed Description

DtException is the generic MAK Exception from which all other Exceptions thrown by MAK products are derived.

DtExceptions must be copyable. DtExceptions must not throw.

Exceptions can be chained, that is, a new exception can be created and passed a pointer to an old exception, to create an exception trace. A pointer is passed as its acceptable to pass no exception.

Constructor & Destructor Documentation

DtException::DtException	(	const char *	errorMessage,
		const DtException *	previousException = 0
	)
throw	(
	)

Default CTOR takes error message and a previous exception, if there is one.

DtException::DtException	(	const char *	errorMessage,
		const char *	functionName,
		const char *	fileName,
		unsigned int	lineNumber,
		const DtException *	previousException = 0
	)
throw	(
	)

CTOR takes error message, a fileName, Function, and line number which is prefixed to the error message.

This CTOR also takes a previous exception if there was one.

DtException::DtException	(	const DtException &	other	)
throw	(
	)

Copy CTOR.

virtual DtException::~DtException	(		)
throw	(
	)

DTOR.

virtual const DtException& DtException::initialException ( ) const throw ( )

virtual

Returns the initial exception in the chain of exceptions.

If this is the only exception in the chain, returns itself.

virtual const DtException* DtException::lastException ( ) const throw ( )

virtual

returns a pointer to a copy of the last exception, if there was one.

If not exception was passed then it returns NULL.

virtual const char* DtException::message ( ) const throw ( )

virtual

Returns a printable description of the error.

DtException& DtException::operator=	(	const DtException &	other	)
throw	(
	)

Assignment Operator.

Referenced by DtTemplatedException< I >::operator=().

virtual DtString DtException::what ( ) const throw ( )

virtual

This function is exactly the same as message() except it returned as a DtString.

virtual DtString DtException::where ( ) const throw ( )

virtual

Returns a printable location of the error.
