Method Detail

merge

public static <T> List<T> merge(List<T> first,
                                List<T> second)

Merges two lists while preserving order. Common sequences are identified in two lists and are output in a merged List in same order as the originals. If a sequence of elements is found in the second List between two common elements, it is inserted between them in the merged list. If a non-overlapping sequence is found in the second List it is appended to the merged List. The method is non-destructive of its arguments. It is assumed that the common elements of the two lists are in the same order, but they are allowed to have intervening non-common elements. The only requirement for element type is that its equals() method is transitive and consistent, as specified by Object.equals().

Type Parameters:

T - element type

Parameters:

first - a sequence of elements

second - a sequence of elements

Returns:

a merged list

append

public static <T> void append(List<T> dest,
                              List<T> source,
                              int from,
                              int toExclusive)

insert

public static <T> void insert(List<T> dest,
                              int insertPos,
                              List<T> source,
                              int from,
                              int toExclusive)
