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:
checkOwner
in classPermissionsDescriptor
- Returns:
- boolean If passed authorization id is owner of the table
