org.apache.uima.resource.metadata.ConfigurationParameter
Completely specifies a configuration parameter on a UIMA resource.
A configuration parameter consists of the following fields:
- Name
- Description
- Type (String, Boolean, Integer, or Float)
- Is the parameter multi-valued?
- Is a value mandatory?
- Overrides (see below)
This interface does not provide access to the value of the parameter - that is a separate piece of metadata associated with the resource.
In an aggregate resource, configuration parameters may override component resources' parameters. This is done by the {@link #getOverrides() overrides} property. Overrides should always bespecified 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.
As with all {@link MetaDataObject}s, a ConfigurationParameter may or may not be modifiable. An application can find out by calling the {@link #isModifiable()} method.
