type GetSGPrm

type GetSGPrm struct {
	Context context.Context

	OID oid.ID
	CID cid.ID

	NetMap    netmap.NetMap
	Container [][]netmap.NodeInfo
}

GetSGPrm groups parameter of GetSG operation.

type SGSource

type SGSource interface {
	// ListSG must list storage group objects in the container. Formed list must be written to destination.
	//
	// Must return any error encountered which did not allow to form the list.
	ListSG(*SearchSGDst, SearchSGPrm) error

	// GetSG must return storage group object for the provided CID, OID,
	// container and netmap state.
	GetSG(GetSGPrm) (*storagegroup.StorageGroup, error)
}

SGSource is a storage group information source interface.

type SearchSGDst

type SearchSGDst struct {
	Objects []oid.ID
}

SearchSGDst groups the target values which Processor expects from SG searching to process.

	Context context.Context

	Container cid.ID

	NodeInfo client.NodeInfo
}

SearchSGPrm groups the parameters which are formed by Processor to search the storage group objects.
