public static final class AccessRule.NoWriteRule extends Object implements AccessRule
Wraps another rule to return a maximum access level of read-only. That is, if the inner rule returns read-write, this rule will return read-only. Otherwise, it returns the same result as the inner rule.

getPermission
public AccessPermission getPermission(Adaptation anAdaptation, Session aSession, SchemaNode aNode)
Description copied from interface:AccessRule
Returns permissions for the specified arguments.Warning: if this
AccessRule
is assigned to atable record
, this method is called in multiple contexts:- To evaluate table "column" permissions;
in this case,
aDataSetOrRecord
is the current dataset. - To evaluate the node permissions of a specific existing record;
in this case,
aDataSetOrRecord
is the current record. - To evaluate the node permissions in a record creation context
(meaning that the record does not exist yet);
in this case,
aDataSetOrRecord
is the current dataset. - Furthermore, if table history is activated, this method will also be invoked in the context of the history view in the first two cases above. In the context of the history view, some fields may be absent and the expected permissions can be different from those in other contexts. Consequently, the implementation of this method may need to check if it is being invoked from the history view. For more information, see Permissions for table history.

- Parameters:
anAdaptation

- current user sessionaNode
- current data model node whose access must be computed; when the permission is requested for the dataset itself (not a particular node), this is the root node- Returns:
