Golang PortRange Examples

Example #1

File: allocator.go Project: qinguoan/vulcan

// NewPortAllocatorCustom creates a PortAllocator over a util.PortRange, calling allocatorFactory to construct the backing store.
func NewPortAllocatorCustom(pr util.PortRange, allocatorFactory allocator.AllocatorFactory) *PortAllocator {
	max := pr.Size
	rangeSpec := pr.String()

	a := &PortAllocator{
		portRange: pr,
	}
	a.alloc = allocatorFactory(max, rangeSpec)
	return a
}

Example #2

File: allocator.go Project: qinguoan/vulcan

// Restore restores the pool to the previously captured state. ErrMismatchedNetwork
// is returned if the provided port range doesn't exactly match the previous range.
func (r *PortAllocator) Restore(pr util.PortRange, data []byte) error {
	if pr.String() != r.portRange.String() {
		return ErrMismatchedNetwork
	}
	snapshottable, ok := r.alloc.(allocator.Snapshottable)
	if !ok {
		return fmt.Errorf("not a snapshottable allocator")
	}
	return snapshottable.Restore(pr.String(), data)
}
