C++
void beginRestore( AcDbDatabase*, const ACHAR*, AcDbDatabase* ) override;
Description
This callback indicates that the Xref was previously unloaded, and now is to be reloaded, but its file has not changed. Instead of loading another copy of the file into memory, the previous settings of the Xref are restored. Purged symbols are un-erased, and the entities in the block are restored. Applications which made changes during the xrefSubcommandUnloadItem() callback for this Xref will need to undo those changes.
Parameters
| Parameters | Description |
|---|---|
| pTo | Passed in pointer to target drawing database |
| pName | Passed in name of the external reference being restored |
| pFrom | Passed in pointer to the drawing that is being XREFd |
