Method Details

convertPollingIntervalString

public static int convertPollingIntervalString(String pollingInterval)

Converts a String which represents a pollingInterval into an int which can be used as delay for Thread.sleep();

Following conversion will happen:

null || "" = -1
500 = 500
1s = 1000 * 1 = 1000
1m = 1000 * 60 = 60000
1h = 1000 * 60 * 60 = 3600000

Parameters:

pollingInterval - interval string, such as '1m' as millisecond value

Returns:

interval in milliseconds

toCommaSeparated

public static String toCommaSeparated(String... strings)

fromCommaSeparated

public static String[] fromCommaSeparated(String commaWords)

getEnumFromString

public static <T extends Enum<T>> T getEnumFromString(Class<T> c,
 String string)

Get an enum value from a string without throwing exception. Enum should be in uppercase to use this method.
