Class PatternMatchingCompositeLineTokenizer

java.lang.Object
  org.springframework.batch.item.file.transform.PatternMatchingCompositeLineTokenizer

All Implemented Interfaces:

LineTokenizer, InitializingBean

public class PatternMatchingCompositeLineTokenizer
extends Object
implements LineTokenizer, InitializingBean

A LineTokenizer implementation that stores a mapping of String patterns to delegate LineTokenizers. Each line tokenizied 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.
