Examples of org.apache.uima.resource.ExternalResourceDescription

org.apache.uima.resource.ExternalResourceDescription
An ExternalResourceDescription object describes a resource that is loaded in the {@link org.apache.uima.resource.ResourceManager} and may be shared between components. Thisobject has four properties:
- A name, used to identify the resource.
- A textual description of the resource.
- A {@link org.apache.uima.resource.ResourceSpecifier} that describes how to create theresource (for simple data resources this will be a {@link org.apache.uima.resource.FileResourceSpecifier} that contains a URL to the data file.
- The name of a Java class that implements the specified interface and which also implements {@link org.apache.uima.resource.SharedResourceObject}.
