获取日志级别 - LogGetLevel

函数简介

获取当前的日志输出级别。

接口名称

LogGetLevel

DLL调用

int32_t LogGetLevel(int64_t instance, int64_t loggerHandle);

参数说明

参数名	类型	说明
instance	长整数型	OLAPlug对象的指针，由 CreateCOLAPlugInterFace 接口生成。
loggerHandle	长整数型	日志实例句柄（0 表示默认实例）。

示例

先 LogSetLevel，再 LogGetLevel 打印核对。

SDK 调用

#include "OLAPlugServer.h"
#include <cstdio>

OLAPlugServer ola;
const int64_t logger = 0; // 默认实例

ola.LogSetLevel(logger, 2); // INFO
int level = ola.LogGetLevel(logger);
std::printf("current level: %d\n", level);

using System;
using OLAPlug;

var ola = new OLAPlugServer();
long logger = 0;

ola.LogSetLevel(logger, 2); // INFO
int level = ola.LogGetLevel(logger);
Console.WriteLine("current level: " + level);

from OLAPlugServer import OLAPlugServer

ola = OLAPlugServer()
logger = 0

ola.LogSetLevel(logger, 2)  # INFO
level = ola.LogGetLevel(logger)
print("current level:", level)

import com.olaplug.OLAPlugServer;

OLAPlugServer ola = new OLAPlugServer();
long logger = 0;

ola.LogSetLevel(logger, 2); // INFO
int level = ola.LogGetLevel(logger);
System.out.println("current level: " + level);

import (
    "fmt"
    "github.com/ola/olaplug/olaplug"
)

ola, _ := olaplug.NewOLAPlugServer("OLAPlug_x64.dll")
defer ola.ReleaseObj()
logger := int64(0)

ola.LogSetLevel(logger, 2) // INFO
level := ola.LogGetLevel(logger)
fmt.Println("current level:", level)

use olaplug::OLAPlugServer;

let ola = OLAPlugServer::new("OLAPlug_x64.dll").unwrap();
let logger = 0i64;

ola.log_set_level(logger, 2); // INFO
let level = ola.log_get_level(logger);
println!("current level: {}", level);

var ola = com("OlaPlug.OlaSoft")
var logger = 0

ola.LogSetLevel(logger, 2) // INFO
var level = ola.LogGetLevel(logger)
traceprint("current level: " + level)

Set ola = CreateObject("OlaPlug.OlaSoft")
logger = 0

ola.LogSetLevel logger, 2
level = ola.LogGetLevel(logger)
TracePrint "current level: " & level

.局部变量 ola, OLAPlug
.局部变量 ret, 整数型
.局部变量 logger, 长整数型
.局部变量 level, 整数型

ola.Create ()
logger ＝ 0

ola.LogSetLevel (logger, 2)  ' INFO
level ＝ ola.LogGetLevel (logger)
调试输出 (“current level：”, level)

import OLAPlugServer;
var ola = OLAPlugServer();
var logger = 0;

ola.LogSetLevel(logger, 2); // INFO
var level = ola.LogGetLevel(logger);
io.print("current level: ", level);

变量 ola <类型 = OLAPlugServer>
ola = 新建 OLAPlugServer
长整数 logger = 0

ola.LogSetLevel(logger, 2)  ' INFO
整数 level = ola.LogGetLevel(logger)
调试输出 ("current level：", level)

#include "OLAPlugServer.h"
#include <cstdio>

OLAPlugServer ola;
int64_t logger = 0;

ola.LogSetLevel(logger, 2); // INFO
int32_t level = ola.LogGetLevel(logger);
std::printf("current level: %d\n", level);

原生 DLL 调用

long instance = CreateCOLAPlugInterFace();
long logger = 0;

LogSetLevel(instance, logger, 2); // INFO
int level = LogGetLevel(instance, logger); // 期望 2

[DllImport("OLAPlug_x64.dll", CallingConvention = CallingConvention.StdCall)]
static extern int LogGetLevel(long ola, long loggerHandle);

long instance = CreateCOLAPlugInterFace();
long logger = 0;

LogSetLevel(instance, logger, 2);
int level = LogGetLevel(instance, logger);

from ctypes import CDLL, c_int, c_int64

ola = CDLL("OLAPlug_x64.dll")
ola.CreateCOLAPlugInterFace.restype = c_int64
instance = ola.CreateCOLAPlugInterFace()
logger = 0

ola.LogSetLevel(instance, logger, 2)
print("current level:", ola.LogGetLevel(instance, logger))

返回值

返回值	说明
（返回值）	当前日志级别（整数型），失败返回 -1。见 LogLevel 枚举：。

注意事项

项目	说明
如果日志系统未初始化	如果日志系统未初始化，返回 -1。
可以用于判断是否需要执行某些调试相关的操作	可以用于判断是否需要执行某些调试相关的操作。
配合使用	配合 LogSetLevel 使用，实现动态调整日志级别。
