Class JepMapper

  • All Implemented Interfaces:
    Mapper

    public class JepMapper
    extends Object
    implements Mapper
    A mapper that uses Jep to calculate the final value. It should be used for numerical values that needs to be transformed before beeing inserted into the database. For example, if a file contains the radius of a spot instead of the diameter, it could be mapped as =2 * col('Radius').

    It can also be used for concatenating string values but syntax with backslashes has better performance. The following mapping expressions are equivalent, but we recommend using the first one:

    \Name\:\ID\
    =col('Name')+':'+col('ID')
    =\Name\+':'+\ID\
