org.springframework.batch.sample.domain.trade.CompositeCustomerUpdateLineTokenizer

All Implemented Interfaces:

StepExecutionListener, StepListener, LineTokenizer

public class CompositeCustomerUpdateLineTokenizer
extends StepExecutionListenerSupport
implements LineTokenizer

Composite LineTokenizer that delegates the tokenization of a line to one of two potential tokenizers. The file format in this case uses one character, either F, A, U, or D to indicate whether or not the line is an a footer record, or a customer add, update, or delete, and will delegate accordingly.
