getDamerauLevenshteinDistance

public static int getDamerauLevenshteinDistance(String s,
                                                String t)

isEmpty

public static boolean isEmpty(CharSequence val)

Check if the CharSequence supplied is empty. A CharSequence is empty when it is null or when the length is 0

Parameters:

val - The stringBuffer to check

Returns:

true if the stringBuffer supplied is empty

isEmpty

public static boolean isEmpty(CharSequence[] strings)

Check if the CharSequence array supplied is empty. A CharSequence array is empty when it is null or when the number of elements is 0

Parameters:

strings - The string array to check

Returns:

true if the string array supplied is empty

isEmpty

public static boolean isEmpty(Object[] array)

Check if the array supplied is empty. An array is empty when it is null or when the length is 0

Parameters:

array - The array to check

Returns:

true if the array supplied is empty

isEmpty

public static boolean isEmpty(List<?> list)

Check if the list supplied is empty. An array is empty when it is null or when the length is 0

Parameters:

list - the list to check

Returns:

true if the supplied list is empty

resolvePassword

public static String resolvePassword(VariableSpace variables,
                                     String password)

Resolves password from variable if it's necessary and decrypts if the password was encrypted

Parameters:

variables - VariableSpace is used for resolving

password - the password for resolving and decrypting

Returns:

resolved decrypted password
