Method Summary

static void	checkAssignable(Class assignableToClass, String argumentName, Class argumentClass) Checks if the argumentClass is assignable to assignableToClass, and if not throws an IllegalArgumentException, otherwise does nothing.
static void	checkAssignable(String methodExecuteName, Class assignableToClass, String argumentName, Class argumentClass) Deprecated. use checkAssignable(Class, String, Class) since we can detect the method name.
static void	checkEmpty(String argumentName, String argument) Checks if the argument is null or an empty String throws an IllegalArgumentException if it is, does nothing if not.
static void	checkEmpty(String methodExecuteName, String argumentName, String argument) Deprecated. use checkEmpty(String, String) instead since we can detect the method name.
static void	checkNull(String argumentName, Object argument) Checks if the argument is null, and if so, throws an IllegalArgumentException, does nothing if not.
static void	checkNull(String methodExecuteName, String argumentName, Object argument) Deprecated. used checkNull(String, Object) instead since we can detect the method name.
static Throwable	getRootCause(Throwable throwable) Attempts to retrieve the root cause of the exception, if it can not be found, the throwable itself is returned.

checkNull

public static void checkNull(String methodExecuteName,
                             String argumentName,
                             Object argument)

Deprecated. used checkNull(String, Object) instead since we can detect the method name.

Checks if the argument is null, and if so, throws an IllegalArgumentException, does nothing if not.

Parameters:

methodExecuteName - the name of the method we are currently executing

argumentName - the name of the argument we are checking for null

argument - the argument we are checking

checkNull

public static void checkNull(String argumentName,
                             Object argument)

Checks if the argument is null, and if so, throws an IllegalArgumentException, does nothing if not.

Parameters:

argumentName - the name of the argument we are checking for null

argument - the argument we are checking

checkEmpty

public static void checkEmpty(String methodExecuteName,
                              String argumentName,
                              String argument)

Deprecated. use checkEmpty(String, String) instead since we can detect the method name.

Checks if the argument is null or an empty String throws an IllegalArgumentException if it is, does nothing if not.

Parameters:

methodExecuteName - the name of the method we are currently executing

argumentName - the name of the argument we are checking for null

argument - the argument we are checking

checkEmpty

public static void checkEmpty(String argumentName,
                              String argument)

Parameters:

argumentName - the name of the argument we are checking for null

argument - the argument we are checking

checkAssignable

public static void checkAssignable(String methodExecuteName,

                                   Class argumentClass)

Deprecated. use checkAssignable(Class, String, Class) since we can detect the method name.

Checks if the argumentClass is assignable to assignableToClass, and if not throws an IllegalArgumentException, otherwise does nothing.

Parameters:

methodExecuteName - the method name of the method, this method is being executed within

assignableToClass - the Class that argumentClass must be assignable to

argumentClass - the argumentClass we are checking
