◆ IOExists()

virtual bool IOExists ( )
pure virtual

IOExists validates your IO object is an IO Node.

ℹ This function is avaliable in RapidCode and RapidSequencer

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.
