DefaultLineMapper (Spring Batch 4.1.4.RELEASE API)

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

类型参数:
T - type of the item
所有已实现的接口:
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.

    从接口复制的说明: LineMapper
    Implementations must implement this method to map the provided line to the parameter type T. The line number represents the number of lines into a file the current line resides.
    指定者:
    mapLine 在接口中 LineMapper<T>
    参数:
    line - to be mapped
    lineNumber - of the current line
    返回:
    mapped object of type T
    抛出:
    java.lang.Exception - if error occurred while parsing.
  - setLineTokenizer
```
public void setLineTokenizer(LineTokenizer tokenizer)
```
  - setFieldSetMapper
```
public void setFieldSetMapper(FieldSetMapper<T> fieldSetMapper)
```
  - afterPropertiesSet
```
public void afterPropertiesSet()
```
    指定者:
    afterPropertiesSet 在接口中 org.springframework.beans.factory.InitializingBean
