org.apache.uima.resource.metadata.ConfigurationParameterDeclarations
The declarations of configuration parameters in a Resource. A Resource can either declare a single list of {@link ConfigurationParameter}s or a list of {@link ConfigurationGroup}s, where each group can contain a list of parameters. When groups are used, the Resource can also declare a list of {@link #getCommonParameters() common parameters} shared by all groups.
