示例1: getBuffer
func getBuffer(w io.Writer) *tempBuffer {
w = getWriter(w)
// If either is nil, something will eventually panic, so we might as well do it here
switch w := w.(type) {
case *bytes.Buffer:
if w == nil {
panic("dagr: getBuffer: target *bytes.Buffer is nil")
}
return &tempBuffer{w, false, int64(w.Len())}
}
if b, ok := tempBuffers.Get().(*tempBuffer); ok {
return b
}
// Bizzaro case: tempBuffers.New didn't work? Something should've panicked by now.
return allocMinimumBuffer()
}
