Syntax

public enum Directive

Fields

Name	Description
Excludes	Indicates that a child of the specified type on the specified AttachTarget MUST NOT exist before this scraper is run. Allows for fallbacks and exclusions on multiple but similar scrapers that can take advantage of pre-existing data. All scrapers are eager to run, and will run immediately after their Requires are fulfilled. That means that exclusions apply only to seeds that exist on the previous seed state, before this scraper is run. In order words, if the Requires of a scraper is fulfilled before all possible Excludes may have appeared, the scraper will run regardless of any Excludes. If the state of the seed tree excludes this scraper after it has already been run, the result will exist for the remainder of the IScrapeContext unless it is culled by an ICuller.
Requires	Indicates that a child of the specified type on the specified AttachTarget MUST exist before this scraper is run. Seed types of this directive are guaranteed to be available when this scraper is run.
