IBlockingDeque.OfferFirst Method

Definition

Overloads

OfferFirst(Object)

Inserts the specified element at the front of this deque if it is possible to do so immediately without violating capacity restrictions, returning true upon success and false if no space is currently available.

OfferFirst(Object, Int64, TimeUnit)

Inserts the specified element at the front of this deque, waiting up to the specified wait time if necessary for space to become available.

OfferFirst(Object)

Inserts the specified element at the front of this deque if it is possible to do so immediately without violating capacity restrictions, returning true upon success and false if no space is currently available.

public bool OfferFirst (Java.Lang.Object? e);

abstract member OfferFirst : Java.Lang.Object -> bool

Parameters

e
Object

the element to add

Returns

Implements

Attributes

Remarks

Inserts the specified element at the front of this deque if it is possible to do so immediately without violating capacity restrictions, returning true upon success and false if no space is currently available. When using a capacity-restricted deque, this method is generally preferable to the #addFirst(Object) addFirst method, which can fail to insert an element only by throwing an exception.
