详细描述

xlight行情解码迭代器

支持以下行情源： QuoteMCType::XLT_SSE_L1 QuoteMCType::XLT_SZSE_L1

成员类型定义说明

StepFunc

using x1::XLTQuoteDecoder::StepFunc = const XLTQuoteItem* (*)(uint8_t*& data, uint32_t& remain, XLTQuoteItem& item)

构造及析构函数说明

XLTQuoteDecoder() [1/2]

x1::XLTQuoteDecoder::XLTQuoteDecoder	(	QuoteMCType	mc_type,
		const void *	msg_data,
		uint32_t	msg_len )

~XLTQuoteDecoder()

x1::XLTQuoteDecoder::~XLTQuoteDecoder ( )

default

XLTQuoteDecoder() [2/2]

x1::XLTQuoteDecoder::XLTQuoteDecoder ( const XLTQuoteDecoder & )

delete

不可拷贝、不可移动

成员函数说明

get_next()

const XLTQuoteItem * x1::XLTQuoteDecoder::get_next

(

)

获取下一条解码后的行情数据

返回

非空指针表示一条有效数据，nullptr 表示遍历结束或构造时 mc_type 不支持

注解

返回的指针在下一次调用 get_next() 后失效（指向内部复用对象）

data 指针的生命周期与构造时传入的 msg_data 一致

operator=()

XLTQuoteDecoder & x1::XLTQuoteDecoder::operator= ( const XLTQuoteDecoder & )

delete
