BaseContext :: permitted - Check access permission
The function returns, whether the application is allowed to call the action passed in sActionName ( true ) or not ( false ). The function is called internally before executing an action or function.
By default, the function returns true . In order to perform permission checks, the permitted() function can be overloaded in a user specialized context class.
When the context handle does not refer to a valid context instance the function throws an exception.
The value is true when the function was executed successfully. Otherwise the value is set to false .
Implementation details
- sActionName
- Action name
The action name is a name of an action implemented in the context class related to the database source or implemented as default action. Actions can be implemented as expressions, as C++ functions or as .NET function.
In order to pass no action name, an empty string ( String () ) may be passed.
