Interface NativeFilter

All Superinterfaces:

Filter

All Known Implementing Classes:

NativeFilterImpl

public interface NativeFilter
extends Filter

This filter should be treated as an extension point that allows the injection of a complex filtering expression defined in the language of the target data store. This can be used, for example, to inject a complex SQL expression that cannot be defined with the available filters.

Native filters are not meant to be used by end users, but instead to be used by developers to support advanced use cases. There should always be a business \ code layer between end users and native filters. Not complying with this rule may introduce security risks, e.g. SQL injections.
