Interface for custom log handler implementation.

ILogHandler interface to ease unit-testing and mocking of loggers.

using UnityEngine;
using System.Collections;
using System.IO;
using System;

public class MyFileLogHandler : ILogHandler { private FileStream m_FileStream; private StreamWriter m_StreamWriter; private ILogHandler m_DefaultLogHandler = Debug.unityLogger.logHandler;

public MyFileLogHandler() { string filePath = Application.persistentDataPath + "/MyLogs.txt";

m_FileStream = new FileStream(filePath, FileMode.OpenOrCreate, FileAccess.ReadWrite); m_StreamWriter = new StreamWriter(m_FileStream);

// Replace the default debug log handler Debug.unityLogger.logHandler = this; }

public void LogFormat(LogType logType, UnityEngine.Object context, string format, params object[] args) { m_StreamWriter.WriteLine(String.Format(format, args)); m_StreamWriter.Flush(); m_DefaultLogHandler.LogFormat(logType, context, format, args); }

public void LogException(Exception exception, UnityEngine.Object context) { m_DefaultLogHandler.LogException(exception, context); } }
