FakeShuffleOrder

Kotlin |Java

@UnstableApi
public final class FakeShuffleOrder implements ShuffleOrder

Fake ShuffleOrder which returns a reverse order. This order is thus deterministic but different from the original order.

Summary

Public fields
`final int`	`length`

Public constructors
`FakeShuffleOrder(int length)`

Public methods
`ShuffleOrder`	`cloneAndClear()` Returns a copy of the shuffle order with all elements removed.
`ShuffleOrder`	`cloneAndInsert(int insertionIndex, int insertionCount)` Returns a copy of the shuffle order with newly inserted elements.
`ShuffleOrder`	`cloneAndRemove(int indexFrom, int indexToExclusive)` Returns a copy of the shuffle order with a range of elements removed.
`int`	`getFirstIndex()` Returns the first index in the shuffle order, or `INDEX_UNSET` if the shuffle order is empty.
`int`	`getLastIndex()` Returns the last index in the shuffle order, or `INDEX_UNSET` if the shuffle order is empty.
`int`	`getLength()` Returns length of shuffle order.
`int`	`getNextIndex(int index)` Returns the next index in the shuffle order.
`int`	`getPreviousIndex(int index)` Returns the previous index in the shuffle order.

public final int length

public FakeShuffleOrder(int length)

public ShuffleOrder cloneAndClear()

Returns a copy of the shuffle order with all elements removed.

public ShuffleOrder cloneAndInsert(int insertionIndex, int insertionCount)

Returns a copy of the shuffle order with newly inserted elements.

Parameters
`int insertionIndex`	The index in the unshuffled order at which elements are inserted.
`int insertionCount`	The number of elements inserted at `insertionIndex`.

Returns
`ShuffleOrder`	A copy of this `ShuffleOrder` with newly inserted elements.

public ShuffleOrder cloneAndRemove(int indexFrom, int indexToExclusive)

Returns a copy of the shuffle order with a range of elements removed.

Parameters
`int indexFrom`	The starting index in the unshuffled order of the range to remove.
`int indexToExclusive`	The smallest index (must be greater or equal to `indexFrom`) that will not be removed.

Returns
`ShuffleOrder`	A copy of this `ShuffleOrder` without the elements in the removed range.

public int getFirstIndex()

Returns the first index in the shuffle order, or INDEX_UNSET if the shuffle order is empty.

public int getLastIndex()

Returns the last index in the shuffle order, or INDEX_UNSET if the shuffle order is empty.

public int getLength()

Returns length of shuffle order.

public int getNextIndex(int index)

Returns the next index in the shuffle order.

Parameters
`int index`	An index.

Returns
`int`	The index after `index`, or `INDEX_UNSET` if `index` is the last element.

public int getPreviousIndex(int index)

Returns the previous index in the shuffle order.

Parameters
`int index`	An index.

Returns
`int`	The index before `index`, or `INDEX_UNSET` if `index` is the first element.
