IOExists()

bool IOExists ( )

pure virtual

IOExists validates your IO object is an IO Node.

Description:

IOExists checks for Digital/Analog In/Out on the Node to confirm that it is in fact an IO node.

Returns

(bool) True if the NODE contains IO, False if it does NOT.

Sample Code:

// -- C++ -- //
if (anIOobject->IOExists())
{ 
 printf("Test Passed: anIOobject is in fact an IO Object.\n"); 
}
else
{ 
 printf("Test Failed: anIOobject does NOT contain any digital or analog IO."); 
}

// -- C# -- //
if (anIOobject.IOExists())
 Console.Writeline("Test Passed: anIOobject is in fact an IO Object.");
else
 Console.Writeline("Test Failed: anIOobject does NOT contain any digital or analog IO.");

Note

A basic Slice IO module without any IO modules attached will return FALSE until a Digital/Analog In/Out slice is attached.
