Description

SetDeleteValue is an overloaded method used to update or remove the node at the path specified in APath. The AValue and DefValue arguments determine whether the node is updated, or removed by calling DeletePath. When AValue and DefValue are equal, this indicates the node value is the default or unassigned value for the node and DeletePath is called to remove the node at APath. Otherwise, SetValue is called to store AValue to the node path.

The overloaded variants allow the AValue and DefValue arguments to contain various data types including String, Int64, Boolean, TRect, or untyped constants.
