org.springframework.batch.item.file.mapping
Class DefaultLineMapper<T>

java.lang.Object
  org.springframework.batch.item.file.mapping.DefaultLineMapper<T>

Type Parameters:

T - type of the item

All Implemented Interfaces:

LineMapper<T>, InitializingBean

public class DefaultLineMapper<T>
extends Object
implements LineMapper<T>, InitializingBean

Two-phase LineMapper implementation consisting of tokenization of the line into FieldSet followed by mapping to item. By default, any exceptions thrown by either delegates will be wrapped in a FlatFileParseException before being rethrown. If finer grained control of exceptions is needed, the LineMapper interface should be implemented directly.
