                            Object[] arguments,

public NormalizedParameters(String message,
                            Object[] arguments)

Method Detail
- getMessage
```
public String getMessage()
```
- getArguments
```
public Object[] getArguments()
```
- getThrowable
```
public Throwable getThrowable()
```
- getThrowableCandidate
```
public static Throwable getThrowableCandidate(Object[] argArray)
```
  Helper method to determine if an Object array contains a Throwable as last element
  
  Parameters:
  
  argArray - The arguments off which we want to know if it contains a Throwable as last element
  
  Returns:
  
  if the last Object in argArray is a Throwable this method will return it, otherwise it returns null
- trimmedCopy
```
public static Object[] trimmedCopy(Object[] argArray)
```
  Helper method to get all but the last element of an array
  
  Parameters:
  
  argArray - The arguments from which we want to remove the last element
  
  Returns:
  
  a copy of the array without the last element
- normalize
```
public static NormalizedParameters normalize(String msg,
                                             Object[] arguments,
                                             Throwable t)
```
  This method serves to normalize logging call invocation parameters. More specifically, if a throwable argument is not supplied directly, it attempts to extract it from the argument array.
