Method Detail

generateTextFile

public static boolean generateTextFile(String fileName,
                                       String fileData)

isBase64Encoded

public static boolean isBase64Encoded(byte[] data)

isBase64Encoded

public static boolean isBase64Encoded(String str)

isExceedingLimit

public static boolean isExceedingLimit(String str,
                                       int limit)

Checks whether the passed string exceeds a limit of number of characters.

Parameters:

str - str

limit - limit

Returns:

the result of comparison, or false if str is null.

isExceedingLimit

public static boolean isExceedingLimit(List<String> strList,
                                       int limit,
                                       int delimiterLength)

Checks the passed string list whether the cumulative length of strings and delimiters between them exceeds a limit of number of characters. For example for list ("one","two","three") with delimiter "," the length of list is calculated 3+1+3+1+5=13

Parameters:

strList - strList

limit - Limit

delimiterLength - delimiterLength - 0 if there is no delimeter.

Returns:

the result of comparison, or false if strList is null.

getFilenameExtension

public static String getFilenameExtension(String fileName)

Return the extension as the substring from the last dot. For input "kuku.txt", "txt" will be returned. If no dot is found or input is null, empty string is returned.

Parameters:

fileName - fileName

Returns:

extension

calculateMD5ByByteArray

public static String calculateMD5ByByteArray(byte[] payload)

calculateMD5ByString

public static String calculateMD5ByString(String data)

Parameters:

data - data

Returns:
