示例1: fetchMachines
// fetchMachines returns a map from top level machine id to machines, where machines[0] is the host
// machine and machines[1..n] are any containers (including nested ones).
//
// If machineIds is non-nil, only machines whose IDs are in the set are returned.
func fetchMachines(st *state.State, machineIds *set.Strings) (map[string][]*state.Machine, error) {
v := make(map[string][]*state.Machine)
machines, err := st.AllMachines()
if err != nil {
return nil, err
}
// AllMachines gives us machines sorted by id.
for _, m := range machines {
if machineIds != nil && !machineIds.Contains(m.Id()) {
continue
}
parentId, ok := m.ParentId()
if !ok {
// Only top level host machines go directly into the machine map.
v[m.Id()] = []*state.Machine{m}
} else {
topParentId := state.TopParentId(m.Id())
machines, ok := v[topParentId]
if !ok {
panic(fmt.Errorf("unexpected machine id %q", parentId))
}
machines = append(machines, m)
v[topParentId] = machines
}
}
return v, nil
}示例2: TestUninitialized
func (stringSetSuite) TestUninitialized(c *C) {
var uninitialized set.Strings
c.Assert(uninitialized.Size(), Equals, 0)
c.Assert(uninitialized.IsEmpty(), Equals, true)
// You can get values and sorted values from an unitialized set.
AssertValues(c, uninitialized)
// All contains checks are false
c.Assert(uninitialized.Contains("foo"), Equals, false)
// Remove works on an uninitialized Strings
uninitialized.Remove("foo")
var other set.Strings
// Union returns a new set that is empty but initialized.
c.Assert(uninitialized.Union(other), DeepEquals, set.NewStrings())
c.Assert(uninitialized.Intersection(other), DeepEquals, set.NewStrings())
c.Assert(uninitialized.Difference(other), DeepEquals, set.NewStrings())
other = set.NewStrings("foo", "bar")
c.Assert(uninitialized.Union(other), DeepEquals, other)
c.Assert(uninitialized.Intersection(other), DeepEquals, set.NewStrings())
c.Assert(uninitialized.Difference(other), DeepEquals, set.NewStrings())
c.Assert(other.Union(uninitialized), DeepEquals, other)
c.Assert(other.Intersection(uninitialized), DeepEquals, set.NewStrings())
c.Assert(other.Difference(uninitialized), DeepEquals, other)
// Once something is added, the set becomes initialized.
uninitialized.Add("foo")
AssertValues(c, uninitialized, "foo")
}
