std::ostream & | operator<< (std::ostream &out, const Holder &holder) |
An abstract base class for storage holders.
Storage holders are edges in the devicegraph.
Holder* storage::Holder::copy_to_devicegraph | ( | Devicegraph * | devicegraph | ) | const |
Copies the holder to the devicegraph.
Does not copy devices. The purpose of the function is to restore parts of the probed devicegraph in the staging devicegraph that were previously deleted.
Source and target devices must already exist in devicegraph. Holder must not exist in devicegraph.
Exception |
|
protected |
Create a holder between source and target in the devicegraph.
Duplicate holders of the same type are not allowed.
The created holder is owned by the devicegraph.

const Device* storage::Holder::get_target | ( | ) | const |
Get the target device of the holder.
sid_t storage::Holder::get_target_sid | ( | ) | const |
Return the storage id (sid) of the target of the holder.
