About manipulators

Manipulator components change the data associated with an Endeca record.

Component	Description
Perl Manipulators	Perl manipulator components perform data transformation, including changing properties and property values, deleting records with particular properties, and so on. Perl manipulators use the Forge API for Perl to perform these tasks.
Java Manipulators	Java manipulator components perform data transformation, including changing properties and property values, deleting records with particular properties, and so on. Java manipulators use Java to perform these tasks. You add Java manipulators to Developer Studio similar to how you add Perl manipulators.
Record Manipulators	Record manipulator components provide support, such as URL extraction, for the Endeca Crawler, that allows you to crawl document hierarchies on a file system or over HTTP or HTTPS. Note: Previous to the introduction of the Perl manipulator component, record manipulators were used to perform property and property value manipulation. This functionality still exists but Endeca highly recommends that you use Perl manipulators instead.
