DefaultLineMapper (Spring Batch 4.1.4.RELEASE API)

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

Type Parameters:
T - type of the item
All Implemented Interfaces:
LineMapper<T>, org.springframework.beans.factory.InitializingBean
```
public class DefaultLineMapper<T>
extends java.lang.Object
implements LineMapper<T>, org.springframework.beans.factory.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.
