Class PatternMatchingCompositeLineTokenizer

java.lang.Object
org.springframework.batch.infrastructure.item.file.transform.PatternMatchingCompositeLineTokenizer
All Implemented Interfaces:
LineTokenizer
public class PatternMatchingCompositeLineTokenizer extends Object implements LineTokenizer
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.
