Class MinMaxPriorityQueue.Builder<B>

java.lang.Object

com.google.common.collect.MinMaxPriorityQueue.Builder<B>

Type Parameters:

B - the upper bound on the eventual type that can be produced by this builder (for example, a Builder<Number> can produce a Queue<Number> or Queue<Integer> but not a Queue<Object>).

Enclosing class:

MinMaxPriorityQueue<E>

@Beta
public static final class MinMaxPriorityQueue.Builder<B>
extends Object

The builder class used in creation of min-max priority queues. Instead of constructing one directly, use MinMaxPriorityQueue.orderedBy(Comparator), MinMaxPriorityQueue.expectedSize(int) or MinMaxPriorityQueue.maximumSize(int).

Since:

8.0

Method Summary

Modifier and Type	Method and Description
<T extends B> MinMaxPriorityQueue<T>	create() Builds a new min-max priority queue using the previously specified options, and having no initial contents.
<T extends B> MinMaxPriorityQueue<T>	create(Iterable<? extends T> initialContents) Builds a new min-max priority queue using the previously specified options, and having the given initial elements.
MinMaxPriorityQueue.Builder<B>	expectedSize(int expectedSize) Configures this builder to build min-max priority queues with an initial expected size of expectedSize.
MinMaxPriorityQueue.Builder<B>	maximumSize(int maximumSize) Configures this builder to build MinMaxPriorityQueue instances that are limited to maximumSize elements.

Method Detail

expectedSize

@CanIgnoreReturnValue
public MinMaxPriorityQueue.Builder<B> expectedSize(int expectedSize)

Configures this builder to build min-max priority queues with an initial expected size of expectedSize.

maximumSize

@CanIgnoreReturnValue
public MinMaxPriorityQueue.Builder<B> maximumSize(int maximumSize)

Configures this builder to build MinMaxPriorityQueue instances that are limited to maximumSize elements. Each time a queue grows beyond this bound, it immediately removes its greatest element (according to its comparator), which might be the element that was just added.

create

public <T extends B> MinMaxPriorityQueue<T> create()

Builds a new min-max priority queue using the previously specified options, and having no initial contents.

create

public <T extends B> MinMaxPriorityQueue<T> create(Iterable<? extends T> initialContents)

Builds a new min-max priority queue using the previously specified options, and having the given initial elements.
