oracle.webcenter.doclib.model
Interface DocumentDescriptorFilter

public interface DocumentDescriptorFilter

A DocumentDescriptorFilter provides an injection point for adding attribute values to a Document or Folder in the Documents Service model layer. This mechanism may be useful in combination with any additional metadata fields defined in the content repository, which need manipulation prior to display by the Documents Service view layer. The DocumentDescriptorFilter does not affect the persisted attribute values.

The java.util.ServiceLoader mechanism is used to load all available filters. An implementer should implement DocumentDescriptorFilter, providing an implementation of filterOnRead. The implementation must then be declared in file, META-INF/services/oracle.webcenter.doclib.model.DocumentDescriptorFilter , that is in a jar that is deployed as part of the WebCenter portal application. The WebCenter Spaces application extensibility mechanism can be used to introduce this dependency to the WebCenter Spaces application.

Since:

11.1.1.6.0
