  - getName
```
String getName()
```
    Return the name of this Logger instance.
    
    返回:
    
    name of this logger instance
  - isTraceEnabled
```
boolean isTraceEnabled()
```
    Is the logger instance enabled for the TRACE level?
    
    返回:
    
    True if this Logger is enabled for the TRACE level, false otherwise.
  - trace
```
void trace(String msg)
```
    Log a message at the TRACE level.
    
    参数:
    
    msg - the message string to be logged
  - trace
```
void trace(String format,
           Object... arguments)
```
    Log a message at the TRACE level according to the specified format and arguments.
    
    This form avoids superfluous string concatenation when the logger is disabled for the TRACE level. However, this variant incurs the hidden (and relatively small) cost of creating an Object[] before invoking the method, even if this logger is disabled for TRACE.
    
    参数:
    
    format - the format string
    
    arguments - a list of 3 or more arguments
  - trace
```
void trace(String msg,
           Throwable t)
```
    Log an exception (throwable) at the TRACE level with an accompanying message.
    
    参数:
    
    msg - the message accompanying the exception
    
    t - the exception (throwable) to log
  - isDebugEnabled
```
boolean isDebugEnabled()
```
    Is the logger instance enabled for the DEBUG level?
    
    返回:
    
    True if this Logger is enabled for the DEBUG level, false otherwise.
  - debug
```
void debug(String msg)
```
    Log a message at the DEBUG level.
    
    参数:
    
    msg - the message string to be logged
  - debug
```
void debug(String format,
           Object... arguments)
```
    Log a message at the DEBUG level according to the specified format and arguments.
    
    This form avoids superfluous string concatenation when the logger is disabled for the DEBUG level. However, this variant incurs the hidden (and relatively small) cost of creating an Object[] before invoking the method, even if this logger is disabled for DEBUG.
    
    参数:
    
    format - the format string
    
    arguments - a list of 3 or more arguments
  - debug
```
void debug(String msg,
           Throwable t)
```
    Log an exception (throwable) at the DEBUG level with an accompanying message.
    
    参数:
    
    msg - the message accompanying the exception
    
    t - the exception (throwable) to log
  - isInfoEnabled
```
boolean isInfoEnabled()
```
    Is the logger instance enabled for the INFO level?
    
    返回:
    
    True if this Logger is enabled for the INFO level, false otherwise.
  - info
```
void info(String msg)
```
    Log a message at the INFO level.
    
    参数:
    
    msg - the message string to be logged
  - info
```
void info(String format,
          Object... arguments)
```
    Log a message at the INFO level according to the specified format and arguments.
    
    This form avoids superfluous string concatenation when the logger is disabled for the INFO level. However, this variant incurs the hidden (and relatively small) cost of creating an Object[] before invoking the method, even if this logger is disabled for INFO.
    
    参数:
    
    format - the format string
    
    arguments - a list of 3 or more arguments
  - info
```
void info(String msg,
          Throwable t)
```
    Log an exception (throwable) at the INFO level with an accompanying message.
    
    参数:
    
    msg - the message accompanying the exception
    
    t - the exception (throwable) to log
  - isWarnEnabled
```
boolean isWarnEnabled()
```
    Is the logger instance enabled for the WARN level?

void warn(String format,
          Object... arguments)
```
    Log a message at the WARN level according to the specified format and arguments.
    
    This form avoids superfluous string concatenation when the logger is disabled for the WARN level. However, this variant incurs the hidden (and relatively small) cost of creating an Object[] before invoking the method, even if this logger is disabled for WARN.
    
    参数:
    
    format - the format string
    
    arguments - a list of 3 or more arguments
  - warn
```
void warn(String msg,
          Throwable t)
```
    Log an exception (throwable) at the WARN level with an accompanying message.
    
    参数:
    
    msg - the message accompanying the exception
    
    t - the exception (throwable) to log
  - isErrorEnabled
```
boolean isErrorEnabled()
```
    Is the logger instance enabled for the ERROR level?
    
    返回:
    
    True if this Logger is enabled for the ERROR level, false otherwise.
  - error
```
void error(String msg)
```
    Log a message at the ERROR level.
