Member Function Documentation

◆ clone()

virtual Subdevice * storage::Subdevice::clone ( ) const
overridevirtual

Implements storage::Holder.

◆ create()

Subdevice * storage::Subdevice::create ( Devicegraph * devicegraph,
const Device * source,
const Device * target )
static

Create a holder of type Subdevice.

Usually this function is not called directly. Functions like PartitionTable::create_partition() or LvmVg::add_lvm_pv() call it.
