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. If finer grained control of exceptions is needed, the LineMapper interface should be implemented directly.
