org.epics.archiverappliance.etl.conversion.ThruNumberAndStringConversion

All Implemented Interfaces:

ConversionFunction

public class ThruNumberAndStringConversion
extends Object
implements ConversionFunction

Generic class for some standard type conversions. Not all type conversions are supported; some type conversions may be completely (or even worse, incompletely) inaccurate for your use case. Only a few of these have been tested and even those only incompletely. In most cases, you should roll your own conversion function and then apply using the ETLDest interface.
