getState()

The getState method is used to define the types of the state variables used by the UDA.

The state variables are passed in to each call of initState, accumulate, merge, and finalResult. The format of the table returned by the getState method is identical to the getArgs and getShape methods.

Example

function getState()
statevars={}
statevars[1] = { "count", integer }
statevars[2] = { "sum",	double	}
return statevars

end
