Class PatternMatchingCompositeLineMapper<T>
java.lang.Object
org.springframework.batch.item.file.mapping.PatternMatchingCompositeLineMapper<T>
- All Implemented Interfaces:
LineMapper<T>
,org.springframework.beans.factory.InitializingBean
public class PatternMatchingCompositeLineMapper<T>
extends Object
implements LineMapper<T>, org.springframework.beans.factory.InitializingBean
A LineMapper
implementation that stores a mapping of String patterns
to delegate LineTokenizer
s as well as a mapping of String patterns to
delegate FieldSetMapper
s. Each line received will be tokenized and
then mapped to a field set.
Both the tokenizing and the mapping work in a similar way. The line will be checked for its matching pattern. If the key matches a pattern in the map of delegates, then the corresponding delegate will be used. Patterns are sorted starting with the most specific, and the first match succeeds.
