Class EntityIdFilter


The base class for all DataSources, especially custom DataSources. It must always be inherited. It provides a lot of core functionality to get configurations, ensure caching and more.

Important: in most cases you will inherit the CustomDataSource DataSource for custom data sources.

The ItemIdFilter DataSource is part of the Standard EAV Data Sources. It will only return the items with the id specified.

Warning: You should always use it in combination with a Content-Type filter, as you want to be sure nobody can just crawl any entity you have in your system!
