}示例2: Write
// Write start add needles to the block, must called after start a transaction.
func (b *SuperBlock) Write(n *needle.Needle) (err error) {
if b.LastErr != nil {
return b.LastErr
}
var incrOffset = needle.NeedleOffset(int64(n.TotalSize))
if err = b.available(incrOffset); err != nil {
return
}
if err = n.Write(b.bw); err != nil {
b.LastErr = err
return
}
b.Offset += incrOffset
return
}
