type InTreeToCSITranslator added in v1.18.0 

type InTreeToCSITranslator interface {
	IsPVMigratable(pv *v1.PersistentVolume) bool
	IsInlineMigratable(vol *v1.Volume) bool
	IsMigratableIntreePluginByName(inTreePluginName string) bool
	GetInTreePluginNameFromSpec(pv *v1.PersistentVolume, vol *v1.Volume) (string, error)
	GetCSINameFromInTreeName(pluginName string) (string, error)
	TranslateInTreePVToCSI(logger klog.Logger, pv *v1.PersistentVolume) (*v1.PersistentVolume, error)
	TranslateInTreeInlineVolumeToCSI(logger klog.Logger, volume *v1.Volume, podNamespace string) (*v1.PersistentVolume, error)
}
