Example 6 with TimeData

use of org.javarosa.core.model.data.TimeData in project javarosa by opendatakit.

the class Recalculate method wrapData.

// droos 1/29/10: we need to come up with a consistent rule for whether the resulting data is determined
// by the type of the instance node, or the type of the expression result. right now it's a mix and a mess
// note a caveat with going solely by instance node type is that untyped nodes default to string!
// for now, these are the rules:
// if node type == bool, convert to boolean (for numbers, zero = f, non-zero = t; empty string = f, all other datatypes -> error)
// if numeric data, convert to int if node type is int OR data is an integer; else convert to double
// if string data or date data, keep as is
// if NaN or empty string, null
