                               T addTo)

flatten

public static <T extends Collection> T flatten(Collection elements,
                               T addTo)

flattenElements

public static <T extends Collection> T flattenElements(Object... elements)

flatten

public static <T extends Collection> T flatten(Collection elements,
                               T addTo,
                               boolean flattenMapsAndArrays)

flatten

public static <T extends Collection> T flatten(Collection elements,
                               T addTo,
                               boolean flattenMaps,
                               boolean flattenArrays)

collectionize

public static Collection collectionize(Object input)

Flattens input collections (including arrays *but* not maps). If input is not a collection wraps it in a collection and returns it.

Parameters:

input - any object

Returns:

collection of flattened input or single input wrapped in a collection.

flatten

public static List flatten(Collection elements,
           boolean flattenMapsAndArrays)

flatten

public static List flatten(Collection elements)

join

public static String join(Collection self,
          String separator)

join

public static String join(Object[] self,
          String separator)

prefix
