Copies data from another node.
Generally this operation assigns value of the source node to the target node.
The operation has special merge semantics for CAB dictionaries:
subnodes that exist in the target but do not exist in the source, will remain untouched;
subnodes that do not exist in the target but exist in the source, will be added to the target;
and to subnodes that exist both in the target and source, Copy operation will be applied recursively.
Syntax
HRESULT Copy( ICabNode* pSrc);
Parameters
- pSrc
- Pointer to ICabNode.
Pointer to a source CAB node.
Return Value
Returns S_OK if operation was successful or error code in other cases.
