public class StdProductCrawler
extends ProductCrawler

A generic Product Crawler for Products. The Crawler is given a root Product Path and it searches through all directories and sub-directories for .met files, which it uses to determine products to ingest into the file manger. The important .met file fields that this crawler requires are:

• FileLocation: directory absolute path to location of product file
• Filename: name of the product file to ingest
• ProductType: the ProductType that will be sent to the file manager for the product file described by the .met file.
