Detailed Description

Class for writing out log information to a file.

Remarks: MAX maintains a log file that contains the text of error / warning / information / debug messages generated by the system and plug-ins. This class is used to work with the log and send messages to it. The log file is placed in the Network directory and is called Max.Log. To access this facility from anywhere in MAX use the pointer returned from the method Interface::Log(). All methods of this class are implemented by the system.

See also: Class Interface.

Member Function Documentation

◆ LogTypes()

virtual DWORD LogTypes ( )

inlinevirtual

Remarks: This method is used to find out what log types are enabled. See System Error Log Message Types. The type values are ORed together to create the value returned.

96 { return valTypes; }

LogSys::valTypes

DWORD valTypes

Definition: log.h:82

◆ SetLogTypes()

virtual void SetLogTypes ( DWORD types )

inlinevirtual

Remarks: This method is used to set the log types that are enabled.

Parameters

types - Sets the type of log messages See System Error Log Message Types.

101 { valTypes = types; }

◆ LogEntry()

virtual void LogEntry	(	DWORD	type,
		BOOL	dialogue,
		const MCHAR *	title,
		const MCHAR *	format,
			...
	)

pure virtual

Remarks: This method is used to log the error.

Parameters

type	- Defines the type of log entry defined in this header file. See System Error Log Message Types. Note that since the System Error Log Message Types are specified as bit flag values, multiple types can be specified (although normally only a single type is specified). If multiple types are specified, the highest severity type that matches with the enabled log types is used. The types in level of severity are error, warn, info, debug.
dialogue	- One of the following values: NO_DIALOG - If this entry is just some information you don't want a dialogue for, or if you are handling the dialogue yourself use this value. DISPLAY_DIALOG - Use this value if you want the message to be displayed in a dialogue. The system will determine if displaying a dialogue is appropriate based on network rendering mode.
title	- This title string is optional. If non NULL, it will be used to define the module.
format	- This parameter (and any other additional arguments that follow) make up the format specification. The format matches the standard C printf() function.

◆ SetQuietMode()

virtual void SetQuietMode ( bool quiet )

pure virtual

Enables or disables 'quiet' mode.

Remarks: When set to quiet mode, the LogSys::LogEntry(...) method will not bring up any dialog boxes. Thus it will act as it does in network rendering mode. That is the error will only be written to the log file.

Note: After setting quiet mode, do not forget to clear it when you are done, since the user will not see any error messages from the renderer while quiet mode is enabled.

Parameters

quiet - true to enable, false to disable.

◆ GetQuietMode()

virtual bool GetQuietMode ( )

pure virtual

Gets the Quiet Mode.

Returns: true if 'quiet' mode is enabled or false if it's disabled.

◆ SetEnabledMode()

virtual void SetEnabledMode ( bool enabled )

pure virtual

Enables or disables 'enabled' mode.

Remarks: When set to not enabled, the LogSys::LogEntry(...) method will not log the message nor bring up any dialog boxes.

Note: After setting to not enabled, do not forget to re-enable it when you are done, since no logging of information will be performed.

Parameters

enabled - true to enable, false to disable.

◆ GetEnabledMode()

virtual bool GetEnabledMode ( )

pure virtual

Gets the 'enabled' mode.

Returns: true if 'enabled' mode is enabled or false if it's disabled.

◆ SetSessionLogName()

virtual void SetSessionLogName ( const MCHAR * logName )

pure virtual

Sets additional output log file on session basis.

This method defines additional log file in specified location. Unlike default max.log file, the output is based on session. If the given file exists, its contents are destroyed.

Parameters

[in] logName - output file name. If an empty (but non-null) string is specified, the additional output log file is disabled. If the logName is not a valid file name, the current additional output log file (if any) will continue to be used.

◆ GetSessionLogName()

virtual const MCHAR* GetSessionLogName ( )

pure virtual

Retrieves the additional output log file name.

Returns: - the output file name set in SetSessionLogName() call or NULL if no file specified.

◆ NetLogName()

virtual const MCHAR* NetLogName ( )

pure virtual

Retrieves the output log file name.

Returns: - the output log file name

◆ Longevity()

virtual int Longevity ( )

inlinevirtual

Returns the conditions under which the log is deleted.

Returns

One of the following values:

SYSLOG_LIFE_EVER - The log is never deleted.
SYSLOG_LIFE_DAYS - This log is maintained for this number of days.
SYSLOG_LIFE_SIZE - The log is maintained until it reaches this many kilobytes (KB).

174 { return logLife; }

LogSys::logLife

int logLife

Definition: log.h:83

◆ SetLongevity()

virtual void SetLongevity ( int type )

inlinevirtual

Sets the conditions under which the log is deleted.

Parameters

type	- One of the following values: SYSLOG_LIFE_EVER - The log is never deleted. SYSLOG_LIFE_DAYS - This log is maintained for this number of days. SYSLOG_LIFE_SIZE - The log is maintained until it reaches this many kilobytes (KB).

181 { logLife = type; }

◆ LogDays()

virtual DWORD LogDays ( )

inlinevirtual

Returns the conditions under which the log is cleared.

Returns

One of the following values:

SYSLOG_LIFE_EVER - The log is never deleted.
SYSLOG_LIFE_DAYS - This log is maintained for this number of days.
SYSLOG_LIFE_SIZE - The log is maintained until it reaches this many kilobytes (KB).

188 { return logDays; }

LogSys::logDays

DWORD logDays

Definition: log.h:84

◆ LogSize()

virtual DWORD LogSize ( )

inlinevirtual

Returns the size of the current log file in kilobytes (KB).

191 { return logSize; }

LogSys::logSize

DWORD logSize

Definition: log.h:85

◆ SetLogDays()

virtual void SetLogDays ( DWORD days )

inlinevirtual

Set the number of days the log is maintained.

Parameters

days	- The number of days to maintain the log. After this many days after creation the log is deleted.

196 { logDays = days; }

◆ SetLogSize()

virtual void SetLogSize ( DWORD size )

inlinevirtual

Set the maximum size in kilobytes (KB) of the log file.

After this size is reached the log file is deleted.

Parameters

size	- The maximum size in kilobytes (KB) of the log file.

201 { logSize = size; }

TCB_SPAN_NAMESPACE_NAME::detail::size

constexpr auto size(const C &c) -> decltype(c.size())

Definition: geom_span.hpp:187

◆ SaveState()

virtual void SaveState ( void )

pure virtual

Remarks: This method is used internally.

◆ LoadState()

virtual void LoadState ( void )

pure virtual

Remarks: This method is used internally.
