Method Detail

removeFirst

int removeFirst(double e1)

Removes the first element that equals e1, returning its deleted position or -1 if the element was not found.

removeLast

int removeLast(double e1)

Removes the last element that equals e1, returning its deleted position or -1 if the element was not found.

addFirst

void addFirst(double e1)

Inserts the specified element at the front of this deque.

Parameters:

e1 - the element to add

addLast

void addLast(double e1)

Inserts the specified element at the end of this deque.

Parameters:

e1 - the element to add

removeFirst

double removeFirst()

Retrieves and removes the first element of this deque. Precondition : the deque is not empty !

Returns:

the head element of this deque.

Throws:

java.lang.AssertionError - if this deque is empty and assertions are enabled.

removeLast

double removeLast()

Retrieves and removes the last element of this deque. Precondition : the deque is not empty !

Returns:

the tail of this deque.

Throws:

java.lang.AssertionError - if this deque is empty and assertions are enabled.

getFirst

double getFirst()

Retrieves, but does not remove, the first element of this deque. Precondition : the deque is not empty !

Returns:

the head of this deque.

Throws:

java.lang.AssertionError - if this deque is empty and assertions are enabled.

getLast

double getLast()

Retrieves, but does not remove, the last element of this deque. Precondition : the deque is not empty !

Returns:

the tail of this deque.

Throws:

java.lang.AssertionError - if this deque is empty and assertions are enabled.

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 container elements.

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.
