PomResultStatus Class Reference

A PomResultStatus instance is a temporary object to which both error codes and instances of status_t can be assigned.
If, once such has been assigned, the result turns out to be a failure, the class will throw an IFail using the specified error.
This is the main difference with ResultStatus: More...

Detailed Description

A PomResultStatus instance is a temporary object to which both error codes and instances of status_t can be assigned.
If, once such has been assigned, the result turns out to be a failure, the class will throw an IFail using the specified error.
This is the main difference with ResultStatus:

• ResultStatus uses the last error on the stack to throw the IFail
• PomResultStatus uses the specified error and puts it on the error stack.

Also, keep in mind that the operator = of this class should be used ONLY if the error message is of no importance or if it does not contain any parameter. If this is not the case, use the constructor with parameters.

ResultStatus ok;
try
{
    //NOTE: No need to check what calls have returned. 
    //      If this is an error, the ResultStatus class will ensure that an exception is thrown.
    ok = callSomeFunction();
    ok = callSomeOtherFunction(); 
    [...]
}
catch ( IFail& ifail )
{
    //Handle the exception here
    [...]
}

Default constructor

PomResultStatus::PomResultStatus

(

int

ifail

)

If the parameter ifail is not ITK_ok, adds the specified error to the error stack and throws an IFail exception.

Note

Use this one if the returned error does not take any parameter

PomResultStatus::PomResultStatus	(	int	ifail,
		const char *	s1,
		const char *	s2 = 0,
		const char *	s3 = 0,
		const char *	s4 = 0,
		const char *	s5 = 0,
		const char *	s6 = 0,
		const char *	s7 = 0
	)

If the parameter ifail is not ITK_ok, adds the specified error to the error stack and throws an IFail exception.

Note

Use this one if the returned error code takes a parameter

virtual PomResultStatus::~PomResultStatus ( )
