Class PatternMatchingCompositeLineTokenizer

java.lang.Object

org.springframework.batch.item.file.transform.PatternMatchingCompositeLineTokenizer

All Implemented Interfaces:

LineTokenizer, org.springframework.beans.factory.InitializingBean

public class PatternMatchingCompositeLineTokenizer
extends java.lang.Object
implements LineTokenizer, org.springframework.beans.factory.InitializingBean

A LineTokenizer implementation that stores a mapping of String patterns to delegate LineTokenizers. Each line tokenized will be checked to see if it matches a pattern. If the line matches a key in the map of delegates, then the corresponding delegate LineTokenizer will be used. Patterns are sorted starting with the most specific, and the first match succeeds.
