AccessPermission

setPermission

public void setPermission(AccessPermission a_Permission)
                   throws WTPropertyVetoException

Sets the value of the attribute: permission; This attribute will be used for checking the access permission for each result.

Supported API: false

WTPropertyVetoException

checkAccess

public boolean checkAccess(Object a_object)
                    throws PersistenceException

Check access of the object. Return false if the current principal does not have READ permission on all of the objects. This method is implemented by call the Access Control service hasAccess() method.

Overrides:

getItemBuilders in class AccessControllerAdapter

Parameters:

a_tableInfos - Vector of concrete TableExpression instances to use to create the Access Control items
