Types ¶
type ExtendedResourceCache ¶
type ExtendedResourceCache struct {
// contains filtered or unexported fields
}
ExtendedResourceCache maintains a global cache of extended resource to device class mappings, based on informer events. For that it implements the cache.ResourceEventHandler interface.
func NewExtendedResourceCache ¶
func NewExtendedResourceCache(logger klog.Logger, handlers ...cache.ResourceEventHandler) *ExtendedResourceCache
NewExtendedResourceCache creates a new ExtendedResourceCache instance. The caller is responsible for registering the instance as a handler of DeviceClass events.
Additional event handlers may be registered here or via AddEventHandler.
func (*ExtendedResourceCache) AddEventHandler ¶
func (c *ExtendedResourceCache) AddEventHandler(handler cache.ResourceEventHandler)
AddEventHandler adds an event handler which gets called after the cache has processed some incoming event. More than one additional event handler may be added. They will be called in the order in which they were registered. GetDeviceClass may be called from those event handlers.
Not thread-safe, must be called *before* adding the cache itself to an informer.
func (*ExtendedResourceCache) GetDeviceClass ¶
func (c *ExtendedResourceCache) GetDeviceClass(resourceName v1.ResourceName) *resourceapi.DeviceClass
GetDeviceClass returns the device class for the given extended resource name. Returns nil if the resource name is not found in the cache.
This (and only this) method may be called on a nil ExtendedResourceCache. The nil instance always returns nil.
func (*ExtendedResourceCache) GetExtendedResource ¶
func (c *ExtendedResourceCache) GetExtendedResource(className string) string
GetExtendedResource returns the extended resource name for the given device class name. Returns empty string if the class name is not found in the cache.
func (*ExtendedResourceCache) OnAdd ¶
func (c *ExtendedResourceCache) OnAdd(obj interface{}, isInInitialList bool)
OnAdd handles the addition of a new device class.
func (*ExtendedResourceCache) OnDelete ¶
func (c *ExtendedResourceCache) OnDelete(obj interface{})
OnDelete handles deletion of a device class.
func (*ExtendedResourceCache) OnUpdate ¶
func (c *ExtendedResourceCache) OnUpdate(oldObj, newObj interface{})
OnUpdate handles updates to an existing device class.
