yctx
, String
func
)
uwp
YAnButton FindAnButtonInContext( YAPIContext

func
)
es
function FindAnButtonInContext(
yctx
,
func
)
The identifier can be specified using several formats:
FunctionLogicalName
ModuleSerialNumber.FunctionIdentifier
ModuleSerialNumber.FunctionLogicalName
ModuleLogicalName.FunctionIdentifier
ModuleLogicalName.FunctionLogicalName
This function does not require that the analog input is online at the time it is invoked. The returned
object is nevertheless valid. Use the method
YAnButton.isOnline()
to test if the analog input is
indeed online at a given time. In case of ambiguity when looking for an analog input by logical name, no
error is notified: the first instance found is returned. The search is performed first by hardware name,
then by logical name.
Parameters :
yctx
a YAPI context
func
a string that uniquely characterizes the analog input
Returns :
a
YAnButton
object allowing you to drive the analog input.
