Package com.zfabrik.resources.provider

Interface IResourceProvider

public interface IResourceProvider

Resource providers provide resources to the resource management system. When asked for a resource the resource management will first check if an instance is already managed. If not it will look for a provider registered for the resource namespace.

Resource providers may be declared as component itself using the component type com.zfabrik.resourceProvider.

For example the "components query provider" (com.zfabrik.components/queryProvider) is declared like this:

 com.zfabrik.component.type=com.zfabrik.resourceProvider
 component.className=com.zfabrik.impl.components.query.QueryProvider
 resourceProvider.namespace=com.zfabrik.components.query
