Constants

const (
	MaxUint          = ^uint(0)
	MaxInt           = int(MaxUint >> 1)
	MaxTotalPriority = MaxInt

Variables

)
View Source 
var Scheme = runtime.NewScheme()

Scheme is the default instance of runtime.Scheme to which types in the Kubernetes API are already registered. TODO: remove this, scheduler should not have its own scheme.

View Source 
var SchemeGroupVersion = schema.GroupVersion{Group: "", Version: runtime.APIVersionInternal}

SchemeGroupVersion is group version used to register these objects TODO this should be in the "scheduler" group

Functions

func RegisterDeepCopies deprecated added in v1.8.0 

func RegisterDeepCopies(scheme *runtime.Scheme) error

RegisterDeepCopies adds deep-copy functions to the given scheme. Public to allow building arbitrary schemes.

Deprecated: deepcopy registration will go away when static deepcopy is fully implemented.
