Arguments

`APath`	Path specifier for the value affected in the method.
`AValue`	Value to store at the specified path.
`DefValue`	Value which indicates the path should be removed instead of updated.
`APTypeInfo`	Pointer to the RTTI type information for the value / default value.

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 DeleteValue. When AValue and DefValue are equal, this indicates the node has the default or unassigned value; DeleteValue is called to remove the node at APath. Otherwise, SetValue is called to store AValue to the specified node path.

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