Class Parameter<T>

java.lang.Object
com.denodo.configuration.Parameter<T>
Type Parameters:
T -
All Implemented Interfaces:
Serializable
Direct Known Subclasses:
CompoundParameter, SimpleParameter
public abstract class Parameter<T> extends Object implements Serializable
Parameters have a name and a value if they are single-valued or a Collection of values if they are multivalued. The type of SimpleParameter values is an Object. The type of all values must be the same. The type of CompoundParameter values is a ParameterStructure which contains Parameter objects. Two implementations of Parameter are provided: As an example consider the "accounts" parameter required by a mail crawler. This parameter specifies which mail accounts should be crawled and it is a multivalued compound parameter. Each value of the "accounts" parameter is a structure of two simple parameters:
  • "login" parameter:single-valued, containing a String
  • "password" parameter: single-valued containing a String
So the "account" parameter contains a Collection of ParameterStructure, each ParameterStructure representing one account to be crawled with one "login" and one "password".
