枚举 PreferredAllocationRequestSlotMatchingStrategy

java.lang.Object

java.lang.Enum<PreferredAllocationRequestSlotMatchingStrategy>

org.apache.flink.runtime.jobmaster.slotpool.PreferredAllocationRequestSlotMatchingStrategy

所有已实现的接口:

Serializable, Comparable<PreferredAllocationRequestSlotMatchingStrategy>, RequestSlotMatchingStrategy

public enum PreferredAllocationRequestSlotMatchingStrategy
extends Enum<PreferredAllocationRequestSlotMatchingStrategy>
implements RequestSlotMatchingStrategy

RequestSlotMatchingStrategy that takes the preferred allocations into account. The strategy will try to fulfill the preferred allocations and if this is not possible, then it will fall back to SimpleRequestSlotMatchingStrategy.

INSTANCE

public static final PreferredAllocationRequestSlotMatchingStrategy INSTANCE

方法详细资料

values

public static PreferredAllocationRequestSlotMatchingStrategy[] values()

按照声明该枚举类型的常量的顺序, 返回 包含这些常量的数组。该方法可用于迭代 常量, 如下所示:

for (PreferredAllocationRequestSlotMatchingStrategy c : PreferredAllocationRequestSlotMatchingStrategy.values())
    System.out.println(c);

返回:

按照声明该枚举类型的常量的顺序返回的包含这些常量的数组

valueOf

public static PreferredAllocationRequestSlotMatchingStrategy valueOf(String name)

返回带有指定名称的该类型的枚举常量。 字符串必须与用于声明该类型的枚举常量的 标识符完全匹配。(不允许有多余 的空格字符。)

参数:

name - 要返回的枚举常量的名称。

返回:

返回带有指定名称的枚举常量

抛出:

IllegalArgumentException - 如果该枚举类型没有带有指定名称的常量

NullPointerException - 如果参数为空值

matchRequestsAndSlots

public Collection<RequestSlotMatchingStrategy.RequestSlotMatch> matchRequestsAndSlots(Collection<? extends PhysicalSlot> slots,
                                                                                      Collection<org.apache.flink.runtime.jobmaster.slotpool.PendingRequest> pendingRequests)

从接口复制的说明: RequestSlotMatchingStrategy
