offerFirstAndReturnToken

Object offerFirstAndReturnToken(E e)

Equivalent to Deque.offerFirst(Object), but returns a token used for fast removal.

Parameters:

e - the element to offer

Returns:

a token suitable for use by remove(Object)

offerLastAndReturnToken

Equivalent to Deque.offerLast(Object), but returns a token used for fast removal.

Parameters:

e - the element to offer

Returns:

a token suitable for use by remove(Object)

removeToken

void removeToken(Object token)

Removes the element associated with the given token.

Parameters:

token - the token returned via offerFirstAndReturnToken(Object) or offerLastAndReturnToken(Object).
