Creating and deploying custom attribute value processor plug-ins

You can deploy custom attribute value processor plug-ins for DDC into the HCL Portal application extension registry. Attribute value processor plug-ins can be used to process the value of an item attribute after the value is determined by the list rendering profile.

About this task

The extension point ID for custom attribute value processor plug-ins is com.ibm.portal.wcm.plr.AttributeValueProcessor.

Individual plug-in implementations implement one of the two following Java interfaces for the object factory responsible for creating the actual attribute value processor instance.
  • com.ibm.portal.wcm.plr.AttributeValueProcessorFactory
  • com.ibm.portal.wcm.plr.AttributeValueOnRequestProcessorFactory

The actual attribute value processor implementations must implement the com.ibm.portal.wcm.plr.AttributeValueProcessor Java interface.

All three interfaces are defined in the public Digital Data Connector SPI. For more information about these interfaces, see The developer HCL Portal SPI documentation.
