Method Details

normalize

public static String normalize(@Nullable
 String value)

isBlank

public static boolean isBlank(@Nullable
 String value)

padLeftZeros

public static String padLeftZeros(String inputString,
 Integer length)

paddedVersionString

public static String paddedVersionString(String input)

jsNumberToString

public static String jsNumberToString(double value)

Formats a number like JavaScript's String(number) (ECMAScript Number::toString), so numeric operands compare like they do in the JS SDK. Double.toString(double) can't be used: before JDK 19 it doesn't always give the shortest digits, and it uses a different notation.

Parameters:

value - the number to format

Returns:

the shortest decimal digits that round-trip to value, in plain notation unless the decimal exponent is 21 or more, or -7 or less (for example "1000", "1.5", "0.000002", "1e+21", "1e-7")
