Method Detail

• public static List combinations(Object[] collections)

  Finds all combinations of items from the given collections.

  Parameters:

  collections - the given collections

  Returns:

  a List of the combinations found

  See Also:

  combinations(Collection)

• @com.github.javaparser.ast.expr.MarkerAnnotationExprDeprecated public static List combinations(Collection collections)

  deprecated:

  use combinations(Iterable)

  Parameters:

  collections - the given collections

• public static List combinations(Iterable collections)

  Finds all combinations of items from the given Iterable aggregate of collections. So, combinations([[true, false], [true, false]]) is [[true, true], [false, true], [true, false], [false, false]] and combinations([['a', 'b'],[1, 2, 3]]) is [['a', 1], ['b', 1], ['a', 2], ['b', 2], ['a', 3], ['b', 3]]. If a non-collection item is given, it is treated as a singleton collection, i.e. combinations([[1, 2], 'x']) is [[1, 'x'], [2, 'x']]. If an empty collection is found within the given collections, the result will be an empty list.

  Parameters:

  collections - the Iterable of given collections

  Returns:

  a List of the combinations found

  Returns:

  the maximum value

• @com.github.javaparser.ast.expr.MarkerAnnotationExprDeprecated public static T max(Collection<T> items)

  deprecated:

  Parameters:

  items - a Collection

  Returns:

  the maximum value

  Since:

• public static T min(T[] items)

  Selects the minimum value found in an array of items, so min([2, 4, 6] as Object[]) == 2.

  Parameters:

  items - an array of items

  Returns:

  the minimum value

• @com.github.javaparser.ast.expr.MarkerAnnotationExprDeprecated public static T min(Collection<T> items)

  deprecated:

• public static Set<List<T>> subsequences(List<T> items)

  Finds all non-null subsequences of a list. E.g. subsequences([1, 2, 3]) would be: [[1, 2, 3], [1, 3], [2, 3], [1, 2], [1], [2], [3]]

  Parameters:

  items - the List of items

  Returns:

  the subsequences from items

• public static Object sum(Object[] items)

  Sums all the items from an array of items.

  Parameters:

  items - an array of items

  Returns:

  the sum of the items

• @com.github.javaparser.ast.expr.MarkerAnnotationExprDeprecated public static Object sum(Collection items)

  deprecated:

  use sum(Iterable)

• public static Object sum(Iterable items)

  Sums all the given items.

  Parameters:

  items - an Iterable of items

  Returns:

  the sum of the item

• public static List<List<T>> tails(Iterable<T> collections)

• public static List transpose(Object[] lists)

  Transposes an array of lists.

  Parameters:

  lists - the given lists

  Returns:

  a List of the transposed lists

  See Also:

  transpose(List)

• public static List transpose(List lists)

  Transposes the given lists. So, transpose([['a', 'b'], [1, 2]]) is [['a', 1], ['b', 2]] and transpose([['a', 'b', 'c']]) is [['a'], ['b'], ['c']].

  Parameters:

  lists - the given lists

  Returns:

  a List of the transposed lists
