Detailed Description

Gadget class.

Library: dbgadget

The IliDataGem class defines gadgets that are only visible during the design phase in Rogue Wave Views Data Access. At run time, they cannot be seen by the user. This class serves as a base class for the IliDataSource class, for example.

Accessors\nAccessors provide a scriptable and uniform way to inspect and modify an object by using its base class methods <tt>IlvValueInterface::queryValue()</tt>, <tt>IlvValueInterface::queryValues()</tt>, <tt>IlvValueInterface::changeValue()</tt>, <tt>IlvValueInterface::changeValues()</tt>.\n\n\nThis class inherits the accessors of its superclass \c IlvGadget and adds the following ones:
