Variables

	// SchemeBuilder defines a SchemeBuilder object.
	SchemeBuilder = runtime.NewSchemeBuilder(addKnownTypes)
	// AddToScheme is used to add stored functions to scheme.
	AddToScheme = SchemeBuilder.AddToScheme
)
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
