Method Detail

removeFirst

int removeFirst(double 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(double 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(double e)

Inserts the specified element at the front of this deque.

addLast

void addLast(double e)

Inserts the specified element at the end of this deque.

removeFirst

double removeFirst()

Retrieves and removes the first element of this deque.

Returns:

the head (first) element of this deque.

removeLast

double removeLast()

Retrieves and removes the last element of this deque.

Returns:

the tail of this deque.

getFirst

double getFirst()

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

Returns:

the head of this deque.

getLast

double getLast()

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

Returns:

the head of this deque.

descendingIterator

java.util.Iterator<DoubleCursor> descendingIterator()

Returns:

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

descendingForEach

<T extends DoubleProcedure> T descendingForEach(T procedure)

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

descendingForEach

<T extends DoublePredicate> T descendingForEach(T predicate)

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