Interface DynamicPropertyRetriever

public interface DynamicPropertyRetriever

Plugins to the dynamic property rendering sections of PropertyRenderingUtility that perform the actual retrieval of the values.

In order to associate implementations of this interface with the rendering code, calls must be made to PropertyRenderingUtility.putDynamicPropertyRetriever(org.rhq.core.domain.configuration.PropertyDynamicType, DynamicPropertyRetriever) to map the property type to the instance.

This functionality is abstracted out to prevent the core-gui module from having to make non-core dependencies. Modules using core-gui can implement this interface using whatever means available, such as accessing a database or making a network hop, without having to modify the core-gui dependencies.
