Method Details

removeFirst

int removeFirst(int e)

Removes the first element that equals e.

Returns:

The deleted element's index or -1 if the element was not found.

removeLast

int removeLast(int e)

Removes the last element that equals e.

Returns:

The deleted element's index or -1 if the element was not found.

addFirst

void addFirst(int e)

Inserts the specified element at the front of this deque.

addLast

void addLast(int e)

Inserts the specified element at the end of this deque.

removeFirst

int removeFirst()

Retrieves and removes the first element of this deque.

Returns:

the head (first) element of this deque.

removeLast

int removeLast()

Retrieves and removes the last element of this deque.

Returns:

the tail of this deque.

getFirst

int getFirst()

Retrieves the first element of this deque but does not remove it.

Returns:

the head of this deque.

getLast

int getLast()

Retrieves the last element of this deque but does not remove it.

Returns:

the head of this deque.

descendingIterator

Iterator<IntCursor> descendingIterator()

Returns:

An iterator over elements in this deque in tail-to-head order.

descendingForEach

<T extends IntProcedure> T descendingForEach(T procedure)

Applies a procedure to all elements in tail-to-head order.

descendingForEach

<T extends IntPredicate> T descendingForEach(T predicate)

Applies a predicate to container elements as long, as the predicate returns true. The iteration is interrupted otherwise.
