type LoadCmdReader struct {
	// contains filtered or unexported fields
}

func NewLoadCmdReader

func NewLoadCmdReader(f io.ReadSeeker, order binary.ByteOrder, nextOffset int64) LoadCmdReader

func (*LoadCmdReader) Next

type LoadCmdUpdater

type LoadCmdUpdater struct {
	LoadCmdReader
}

func NewLoadCmdUpdater
