Method Details

cutOnMaxSizeAndJoinStrings

public static String cutOnMaxSizeAndJoinStrings(Collection<String> collectionToJoin,
 String moreThanMaxElementsMessage)

joins all elements of the collection using a line break. if there are more elements in collectionToJoin than defined in maxSize, the list will be shortened to a size of MAX_SIZE and the message in moreThanMaxElementsMessage will be appended at the end. Note: use the placeholder %s in moreThanMaxElementsMessage if you want to include the number of skipped records in the message

Parameters:

collectionToJoin - the strings to join

moreThanMaxElementsMessage - the message to append when the collection is bigger than maxSize

cutOnMaxSizeAndJoinStrings

public static <T> String cutOnMaxSizeAndJoinStrings(Collection<T> collectionToJoin,
 Function<T,String> transformerFunction,
 String moreThanMaxElementsMessage)

behaves the same way as cutOnMaxSizeAndJoinStrings(Collection, String) except that it accepts any type of Collection which will be transformed to a string Collection using the given transformerFunction . Using this method probably results in a better performance than transforming the Collection yourself because it will be shortened, if necessary, before the transformation

Parameters:

collectionToJoin - the strings to join

transformerFunction - a function which must return a String

moreThanMaxElementsMessage - the message to append when the collection is bigger than maxSize

joinOnLineBreaks

public static String joinOnLineBreaks(String... strings)

joinOnLineBreaks

public static String joinOnLineBreaks(Iterable<String> strings)
