MinMaxPriorityQueue.Builder (Guava: Google Core Libraries for Java 30.1.1-jre API)乐学网一站式学习平台

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

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	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.
