Interface Mapper

All Known Implementing Classes:

ColumnMapper, CompoundMapper, ConstantMapper, CropStringMapper, JepMapper, NullIfExceptionMapper

public interface Mapper

Represents a mapping expression that gets a single value from a line of data. A typical mapping expression holds a reference to the column number or name, for example:

\1\
\row\
Row: \row\, Col:\col\
=2 * col('Radius')

The actual syntax for the mapping string depends on the parser used.
