User-defined filter

User-defined filter functions allow you to manipulate data obtained from a source in various ways.

User-defined filter functions allow you to manipulate data obtained from a source in various ways. For example, a filter can:

  • Process a compressed file in a compression format not natively supported by OpenText™ Analytics Database.

  • Take UTF-16-encoded data and transcode it to UTF-8 encoding.

  • Perform search-and-replace operations on data before it is loaded into the database.

You can also process data through multiple filters before it is loaded into the database. For instance, you could unzip a file compressed with GZip, convert the content from UTF-16 to UTF-8, and finally search and replace certain text strings.

If you implement a UDFilter, you must also implement a corresponding FilterFactory.

See UDFilter class and FilterFactory class for API details.
