java.lang.Object net.sf.basedb.util.jep.RawChannelFunction
public class RawChannelFunction
A JEP function class that adds a rawCh(int)
function to a
JEP expression parser. The function will look up the (possible transformed)
intensity value for the given channel. For example: rawCh(1)
Note! This function always return the values as they are stored in
the database. Use ChannelFunction
if you need the untransformed
intensity values.
To be able to use this function it must be registered with the JEP
parser and, before the expression is evaluated, a SqlResult
object must be set.
