Constructor Detail

ListSlice

public ListSlice(int sliceBeginIndex,
                 int sliceEndIndex)

Constructs a new slice for a given list.

Parameters:

sliceBeginIndex - the index from which this slice starts in the list.

sliceEndIndex - the index to which this slice ends in the list.

ListSlice

public ListSlice(int sliceBeginIndex,
                 int sliceEndIndex,
                 int originalListSize)

Constructs a new slice for a given list.

Parameters:

sliceBeginIndex - the index from which this slice starts in the list.

sliceEndIndex - the index to which this slice ends in the list.

originalListSize - the size of the list this slice comes from.

ListSlice

public ListSlice(int sliceBeginIndex,
                 int sliceEndIndex,
                 List<? extends T> originalList)

Constructs a new slice for a given list.

Parameters:

sliceBeginIndex - the index from which this slice starts in the list.

sliceEndIndex - the index to which this slice ends in the list.

originalList - the list from which this slice comes from.

ListSlice

public ListSlice(Collection<? extends T> collection)

Constructs a new list slice with all the items of the specified collection. This slice will cover the whole specified collection; this is it represents a whole list of the specified collection and as such the original list size is equal to its real size.

Parameters:

collection - a collection of items of type T
