checkOwner
public boolean checkOwner(java.lang.String authorizationId)
throws StandardException
- Description copied from class:
PermissionsDescriptor
- This method checks if the passed authorization id is same as the owner
of the object on which this permission is defined. This method gets
called by create view/constraint/trigger to see if this permission
needs to be saved in dependency system for the view/constraint/trigger.
If the same user is the owner of the the object being accessed and the
newly created object, then no need to keep this privilege dependency
- Specified by:

in class PermissionsDescriptor
- Returns:
- boolean If passed authorization id is owner of the table
- Throws:
StandardException
- See Also:
PermissionsDescriptor.checkOwner(java.lang.String)
