Struct FrameDecoder

zinterceptor/framedecoder.go:307–316

FrameDecoder A decoder that splits the received ByteBufs dynamically by the value of the length field in the message. It is particularly useful when you decode a binary message which has an integer header field that represents the length of the message body or the whole message. ziface.Len

// FrameDecoder is a decoder based on the LengthField pattern.
type FrameDecoder struct {
	ziface.LengthField // Basic properties inherited from ILengthField

	LengthFieldEndOffset   int   // Offset of the end position of the length field (LengthFieldOffset+LengthFieldLength) (长度字段结束位置的偏移量)
	failFast               bool  // Fast failure (快速失败)
	discardingTooLongFrame bool  // true indicates discard mode is enabled, false indicates normal working mode (true 表示开启丢弃模式，false 正常工作模式)
	tooLongFrameLength     int64 // When the length of a packet exceeds maxLength, discard mode is enabled, and this field records the length of the data to be discarded (当某个数据包的长度超过maxLength，则开启丢弃模式，此字段记录需要丢弃的数据长度)
	bytesToDiscard         int64 // Records how many bytes still need to be discarded (记录还剩余多少字节需要丢弃)
	in                     []byte
}
