Method Detail

nullIfBlank

public static java.lang.String nullIfBlank(java.lang.String value)

Swap null for blank text values.

Parameters:

value - an input string that may or may not be entirely whitespace

Returns:

null if the string is entirely whitespace, otherwise the input value

isBlank

public static boolean isBlank(java.lang.String value)

A checker for whether or not the input value is entirely whitespace. This is slightly more aggressive than the android TextUtils#isEmpty method, which only returns true for null or "".

Parameters:

value - a possibly blank input string value

Returns:

true if and only if the value is all whitespace, null, or empty

removeSpacesAndHyphens

public static java.lang.String removeSpacesAndHyphens(java.lang.String cardNumberWithSpaces)

Converts a card number that may have spaces between the numbers into one without any spaces. Note: method does not check that all characters are digits or spaces.

Parameters:

cardNumberWithSpaces - a card number, for instance "4242 4242 4242 4242"

Returns:

the input number minus any spaces, for instance "4242424242424242". Returns null if the input was null or all spaces.
