| * Completely specifies a configuration parameter on a UIMA resource. |
| * <p> |
| * A configuration parameter consists of the following fields: |
| * <ul> |
| * <li>Name</li> |
| * <li>Description</li> |
| * <li>Type (String, Boolean, Integer, Long, Float or Double)</li> |
| * <li>Is the parameter multi-valued?</li> |
| * <li>Is a value mandatory?</li> |
| * <li>Overrides (see below)</li> |
| * </ul> |
| * <p> |
| * This interface does not provide access to the value of the parameter - that is a separate piece |
| * of metadata associated with the resource. |
| * <p> |
| * In an aggregate resource, configuration parameters may override component resources' parameters. |
| * This is done by the {@link #getOverrides() overrides} property. Overrides should always be |
| * specified for aggregate resources. If no overrides are specified, the default behavior is to |
| * override any parameter with the same name in any component resource. However, this usage is |
| * discouraged and will generate a warning in the log file; it exists for backwards compatibility |
| * purposes. |
| * <p> |
| * As with all {@link MetaDataObject}s, a <code>ConfigurationParameter</code> may or may not be |
| * modifiable. An application can find out by calling the {@link #isModifiable()} method. |
