Method Detail

checkNull

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

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

checkEmpty

public static void checkEmpty(java.lang.String methodExecuteName,
                              java.lang.String argumentName,
                              java.lang.String argument)

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

checkAssignable

public static void checkAssignable(java.lang.String methodExecuteName,
                                   java.lang.Class assignableToClass,
                                   java.lang.String argumentName,
                                   java.lang.Class argumentClass)

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

argumentName - - the name of the argument we are checking

checkValidInteger

public static java.lang.Integer checkValidInteger(java.lang.String methodExecuteName,
                                                  java.lang.String argumentName,

Parameters:

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

argumentName - - the name of the argument we are checking

argument - - the actual argument we are checking to see if its a valid Integer

Returns:
