Method Details

offer

public final boolean offer(@NonNull T e)

Description copied from interface: SimpleQueue

Atomically enqueue a single value.

Specified by:

offer in interface SimpleQueue<T>

Parameters:

e - the value to enqueue, not null

Returns:

true if successful, false if the value was not enqueued likely due to reaching the queue capacity)

offer

public final boolean offer(@NonNull T v1,
 @NonNull T v2)

Description copied from interface: SimpleQueue

Atomically enqueue two values.

Specified by:

offer in interface SimpleQueue<T>

Parameters:

v1 - the first value to enqueue, not null

v2 - the second value to enqueue, not null

Returns:

true if successful, false if the value was not enqueued likely due to reaching the queue capacity)
